Ten Simple Rules for Writing a Literature Review

Marco pautasso.

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

• interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
• an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
• a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

• keep track of the search items you use (so that your search can be replicated [10] ),
• keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
• use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
• define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
• do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

• discussing in your review the approaches, limitations, and conclusions of past reviews,
• trying to find a new angle that has not been covered adequately in the previous reviews, and
• incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

• be thorough,
• use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
• look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

• the major achievements in the reviewed field,
• the main areas of debate, and
• the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

Writing a Literature Review

Welcome to the Purdue OWL

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

• Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

• Make sure your research question is not too broad or too narrow.  Is it manageable?
• Begin writing down terms that are related to your question. These will be useful for searches later.
• If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. 

Where to find databases:

• use the tabs on this guide
• Find other databases in the Nursing Information Resources web page
• More on the Medical Library web page
• ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

• Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
• Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
• Review the abstracts of research studies carefully. This will save you time.
• Use the bibliographies and references of research studies you find to locate others.
• Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
• Ask your librarian for help at any time.
• Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

• What was the research question of the study you are reviewing? What were the authors trying to discover?
• Was the research funded by a source that could influence the findings?
• What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
• Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
• If there are conflicting studies, why do you think that is?
• How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

• Review the abstracts carefully.  
• Keep careful notes so that you may track your thought processes during the research process.
• Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

What is a literature review?

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

What is the purpose of literature review?

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

1. Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 

2. Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.

3. Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Frequently asked questions

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic.

By:  Derek Jansen (MBA) & Kerryn Warren (PhD) | June 2020 (Updated May 2023)

If you’re faced with writing a dissertation or thesis, chances are you’ve encountered the term “literature review” . If you’re on this page, you’re probably not 100% what the literature review is all about. The good news is that you’ve come to the right place.

What is a literature review?

The word “literature review” can refer to two related things that are part of the broader literature review process. The first is the task of  reviewing the literature  – i.e. sourcing and reading through the existing research relating to your research topic. The second is the  actual chapter  that you write up in your dissertation, thesis or research project. Let’s look at each of them:

Reviewing the literature

The first step of any literature review is to hunt down and  read through the existing research  that’s relevant to your research topic. To do this, you’ll use a combination of tools (we’ll discuss some of these later) to find journal articles, books, ebooks, research reports, dissertations, theses and any other credible sources of information that relate to your topic. You’ll then  summarise and catalogue these  for easy reference when you write up your literature review chapter. 

The literature review chapter

The second step of the literature review is to write the actual literature review chapter (this is usually the second chapter in a typical dissertation or thesis structure ). At the simplest level, the literature review chapter is an  overview of the key literature  that’s relevant to your research topic. This chapter should provide a smooth-flowing discussion of what research has already been done, what is known, what is unknown and what is contested in relation to your research topic. So, you can think of it as an  integrated review of the state of knowledge  around your research topic. 

What’s the purpose of a literature review?

The literature review chapter has a few important functions within your dissertation, thesis or research project. Let’s take a look at these:

Purpose #1 – Demonstrate your topic knowledge

The first function of the literature review chapter is, quite simply, to show the reader (or marker) that you  know what you’re talking about . In other words, a good literature review chapter demonstrates that you’ve read the relevant existing research and understand what’s going on – who’s said what, what’s agreed upon, disagreed upon and so on. This needs to be  more than just a summary  of who said what – it needs to integrate the existing research to  show how it all fits together  and what’s missing (which leads us to purpose #2, next). 

Purpose #2 – Reveal the research gap that you’ll fill

The second function of the literature review chapter is to  show what’s currently missing  from the existing research, to lay the foundation for your own research topic. In other words, your literature review chapter needs to show that there are currently “missing pieces” in terms of the bigger puzzle, and that  your study will fill one of those research gaps . By doing this, you are showing that your research topic is original and will help contribute to the body of knowledge. In other words, the literature review helps justify your research topic.  

Purpose #3 – Lay the foundation for your conceptual framework

The third function of the literature review is to form the  basis for a conceptual framework . Not every research topic will necessarily have a conceptual framework, but if your topic does require one, it needs to be rooted in your literature review. 

For example, let’s say your research aims to identify the drivers of a certain outcome – the factors which contribute to burnout in office workers. In this case, you’d likely develop a conceptual framework which details the potential factors (e.g. long hours, excessive stress, etc), as well as the outcome (burnout). Those factors would need to emerge from the literature review chapter – they can’t just come from your gut! 

So, in this case, the literature review chapter would uncover each of the potential factors (based on previous studies about burnout), which would then be modelled into a framework. 

Purpose #4 – To inform your methodology

The fourth function of the literature review is to  inform the choice of methodology  for your own research. As we’ve  discussed on the Grad Coach blog , your choice of methodology will be heavily influenced by your research aims, objectives and questions . Given that you’ll be reviewing studies covering a topic close to yours, it makes sense that you could learn a lot from their (well-considered) methodologies.

So, when you’re reviewing the literature, you’ll need to  pay close attention to the research design , methodology and methods used in similar studies, and use these to inform your methodology. Quite often, you’ll be able to  “borrow” from previous studies . This is especially true for quantitative studies , as you can use previously tried and tested measures and scales. 

How do I find articles for my literature review?

Finding quality journal articles is essential to crafting a rock-solid literature review. As you probably already know, not all research is created equally, and so you need to make sure that your literature review is  built on credible research . 

We could write an entire post on how to find quality literature (actually, we have ), but a good starting point is Google Scholar . Google Scholar is essentially the academic equivalent of Google, using Google’s powerful search capabilities to find relevant journal articles and reports. It certainly doesn’t cover every possible resource, but it’s a very useful way to get started on your literature review journey, as it will very quickly give you a good indication of what the  most popular pieces of research  are in your field.

One downside of Google Scholar is that it’s merely a search engine – that is, it lists the articles, but oftentimes  it doesn’t host the articles . So you’ll often hit a paywall when clicking through to journal websites. 

Thankfully, your university should provide you with access to their library, so you can find the article titles using Google Scholar and then search for them by name in your university’s online library. Your university may also provide you with access to  ResearchGate , which is another great source for existing research. 

Remember, the correct search keywords will be super important to get the right information from the start. So, pay close attention to the keywords used in the journal articles you read and use those keywords to search for more articles. If you can’t find a spoon in the kitchen, you haven’t looked in the right drawer. 

Need a helping hand?

How should I structure my literature review?

Unfortunately, there’s no generic universal answer for this one. The structure of your literature review will depend largely on your topic area and your research aims and objectives.

You could potentially structure your literature review chapter according to theme, group, variables , chronologically or per concepts in your field of research. We explain the main approaches to structuring your literature review here . You can also download a copy of our free literature review template to help you establish an initial structure.

In general, it’s also a good idea to start wide (i.e. the big-picture-level) and then narrow down, ending your literature review close to your research questions . However, there’s no universal one “right way” to structure your literature review. The most important thing is not to discuss your sources one after the other like a list – as we touched on earlier, your literature review needs to synthesise the research , not summarise it .

Ultimately, you need to craft your literature review so that it conveys the most important information effectively – it needs to tell a logical story in a digestible way. It’s no use starting off with highly technical terms and then only explaining what these terms mean later. Always assume your reader is not a subject matter expert and hold their hand through a journe y of the literature while keeping the functions of the literature review chapter (which we discussed earlier) front of mind.

Write a Literature Review in a Day: Yes, It’s Possible, and It’s Actually Fun

Literature reviews: they are every writer’s least favorite part of writing.

Still, they are a fundamental aspect of scholarly work. They prove that a writer has scoured previous research on a topic, evaluated it, and demonstrated why their own research has merit.

After writing enough of these in grad school, I’ve decided to create a guide to help writers answer the question of “how to write a literature review in a day.”

I’ve also gathered helpful info from other academic and educational sources to further inspire.

After reading this article, you will know how to:

• Find the right, relevant literature.
• Properly organize and catalog works you gather.
• Develop a pattern out of and find gaps in accumulated research.
• Write a stellar review.

Now let’s get down to it.

First Things First: What Is a Literature Review?

A literature review proves that an individual is aware of what other researchers, or “giants” in their field have said on the subject.

As such, lit reviews will consist of literature from other researchers discussing a chosen topic. This literature can come from books, articles, reports, or websites.

As this YouTube video proclaims, academic writing involves “ standing on the shoulders of giants .”

But a lit review will not just be a list of academic references. That can fall into plagiarism territory, which you can learn about in this article .

Okay, but What Is Its Purpose?

Basically, they help you prove your point. That’s why I see them as jigsaw puzzles whose pieces are scattered across other scholarly work.

When you are scanning through other works, you are looking for those jigsaw pieces or patterns and gaps in prior research that you will address. When you finish writing, your puzzle will represent what other researchers have missed.

Structure of a Literature Review

Fortunately, they follow the typical format of intro-body-conclusion .

The intro of a lit review will introduce the paper’s topic and the key concepts the writer will explore.

The body is where all the jigsaw puzzles will be addressed, including:

• What have other researchers said about this topic?
• What is your interpretation of their findings?
• How does the prior research add to the topic’s significance?
• Is there a pattern? Or is there a gaping hole in the research?

And the conclusion will wrap up your arguments.

5 Steps to Write a Literature Review in a Day

1. Find the Relevant Literature

Estimated time: 1 hour

First up is finding a few relevant texts.

My favorite databases are Google Scholar, my library’s database, JSTOR, and Scorpus.

It’s important to distinguish formal vs. informal works, which you can read about here .

I consider effective keywords when searching for sources. These will be words similar to my topic.

2. Read SMARTLY

Estimated time: 1-2 hours

Yes, you’ll need to read, but the trick is to read smartly .

When you type in your keywords and are brought to an article, skim through the abstract and look for:

• The key concepts
• The overall findings
• The gap in the research (or the jigsaw pieces)

This will cut down your reading time tremendously!

In this video, the researcher shares a tough truth: “You HAVE to do reading.”

Some people are very restless and it can be difficult for them to focus. Reading smartly can reduce the time you spent studying.

3. Organize Your Findings

Estimated time: 1-2 hours (combined with step 2)

New Zealand ecologist and researcher Francis J. Burdon claims that a “ poorly executed ” lit review is one that has no “ adequate guidance .” Your material has no worth if not organized!

Often PhD candidates will begin their thesis with a literature review, but this can be poorly executed without adequate guidance. A new guide @MethodsEcolEvol looks to be a very useful resource providing a roadmap for scientists at all career stages https://t.co/k1yjQEF9td — Francis J. Burdon (@frank_burdon) July 1, 2021

While you’re going through articles, pull up either a Microsoft Excel or Google Sheets document to log all of your findings. Include the author and title for all works.

Another good tip is to add additional columns that categorize the findings by relevant keyword, methodology used, and key concept.

The last column for the organized sheet is the “main argument” of the article. Here, summarize the article’s findings in a few sentences.

4. Synthesize!

Estimated time: 2 hours

Now here comes the fun part (at least, to me!). It’s time to synthesize , a fancy word for putting those jigsaw pieces together.

Look over the main arguments and search for any common themes, patterns, contradictions, and weaknesses.

To help you settle on a structure from your findings, literature reviews are usually structured in the following ways:

Chronologically: These are written from when the research began to where it is now.

Thematic: These are organized by common sub themes found in research.

Methodological: These are structured by different academic frameworks used, including different styles of research (i.e., quantitative vs. qualitative).

In this YouTube video the online writing professor, David Taylor, makes a comforting point: “The answers are already out there.”

Everything you need is already written; your job is to put it all together.

5. Write It!

Estimated time: 3+ hours (depending on experience)

All you need to do now is write! I find that crafting a brief outline of which author I’ll mention first and then next helps me start.

In addition, Amina Yonis, a PhD graduate at University of College London, lays out a good format to remember when writing your lit review: background, narrower categories, focus and then hypothesis.

• American literature & culture: American literature
• List of academic databases and search engines

It’s not so bad, is it?

See? Writing a literature review doesn’t have to be a scary task!

The only other thing to keep in mind with lit reviews is plagiarism, as you will be referencing many other authors’ work.

Don’t worry, though — you can use this handy plagiarism tool here to make sure your content is 100% original.

Take these steps into account pre-writing and you’ll have a stellar review!

A literature review is a review and synthesis of existing research on a topic or research question. A literature review is meant to analyze the scholarly literature, make connections across writings and identify strengths, weaknesses, trends, and missing conversations. A literature review should address different aspects of a topic as it relates to your research question. A literature review goes beyond a description or summary of the literature you have read.

What is a Literature Review?

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field. 

A literature review should: 

• Provide a comprehensive and updated review of the literature;
• Explain why this review has taken place;
• Articulate a position or hypothesis;
• Acknowledge and account for conflicting and corroborating points of view

From  S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

• Demonstrate how a study fills a gap in research
• Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

• Organizes or describes a topic
• Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

• It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
• It may be too focused. Some niche studies may miss the bigger picture.
• It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
• It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

Here are some other questions to ask yourself before beginning your literature search:

• Is there a page limit or page requirement? About how many citations do you need?
• Consider whether your review will encompass  all relevant material  or if you’ll focus on more recent sources (e.g., the last five years).
• What is your focus—theoretical issues, methodological approaches, qualitative vs. quantitative?
• Do you need to set any limitations, such as age, gender, location, nationality, etc.?

Before you can begin searching for literature, you need to decide what types of resources you will be searching.

If you'd like to perform a search that looks across different media, start with the scholarly databases . This is a fantastic starting place as databases have collected and curated relevant resources all in one place for more efficient searching.

6 New Books We Recommend This Week

Suggested reading from critics and editors at The New York Times.

• Share full article

It’s a happy coincidence that we recommend Becca Rothfeld’s essay collection “All Things Are Too Small” — a critic’s manifesto “in praise of excess,” as her subtitle has it — in the same week that we also recommend Justin Taylor’s maximalist new novel “Reboot,” an exuberant satire of modern society that stuffs everything from fandom to TV retreads to the rise of conspiracy culture into its craw. I don’t know if Rothfeld has read Taylor’s novel, but I get the feeling she would approve. Maybe you will too: In the spirit of “more, bigger, louder,” why not pick those up together?

Our other recommendations this week include a queer baseball romance novel, an up-to-the-minute story about a widower running for the presidency of his local labor union, a graphic novelist’s collection of spare visual stories and, in nonfiction, a foreign policy journalist’s sobering look at global politics in the 21st century. Happy reading. — Gregory Cowles

REBOOT Justin Taylor

This satire of modern media and pop culture follows a former child actor who is trying to revive the TV show that made him famous. Taylor delves into the worlds of online fandom while exploring the inner life of a man seeking redemption — and something meaningful to do.

“His book is, in part, a performance of culture, a mirror America complete with its own highly imagined myths, yet one still rooted in the Second Great Awakening and the country’s earliest literature. It’s a performance full of wit and rigor.”

From Joshua Ferris’s review

Pantheon | $28

YOU SHOULD BE SO LUCKY Cat Sebastian

When a grieving reporter falls for the struggling baseball player he’s been assigned to write about, their romance is like watching a Labrador puppy fall in love with a pampered Persian cat: all eager impulse on one side and arch contrariness on the other.

“People think the ending is what defines a romance, and it does, but that’s not what a romance is for. The end is where you stop, but the journey is why you go. … If you read one romance this spring, make it this one.”

From Olivia Waite’s romance column

Avon | Paperback, $18.99

ALL THINGS ARE TOO SMALL: Essays in Praise of Excess Becca Rothfeld

A striking debut by a young critic who has been heralded as a throwback to an era of livelier discourse. Rothfeld has published widely and works currently as a nonfiction book critic for The Washington Post; her interests range far, but these essays are united by a plea for more excess in all things, especially thought.

“Splendidly immodest in its neo-Romantic agenda — to tear down minimalism and puritanism in its many current varieties. … A carnival of high-low allusion and analysis.”

From David Gates’s review

Metropolitan Books | $27.99

THE RETURN OF GREAT POWERS: Russia, China, and the Next World War Jim Sciutto

Sciutto’s absorbing account of 21st-century brinkmanship takes readers from Ukraine in the days and hours ahead of Russia’s invasion to the waters of the Taiwan Strait where Chinese jets flying overhead raise tensions across the region. It’s a book that should be read by every legislator or presidential nominee sufficiently deluded to think that returning America to its isolationist past or making chummy with Putin is a viable option in today’s world.

“Enough to send those with a front-row view into the old basement bomb shelter. … The stuff of unholy nightmares.”

From Scott Anderson’s review

Dutton | $30

THE SPOILED HEART Sunjeev Sahota

Sahota’s novel is a bracing study of a middle-aged man’s downfall. A grieving widower seems to finally be turning things around for himself as he runs for the top job at his labor union and pursues a love interest. But his election campaign gets entangled in identity politics, and his troubles quickly multiply.

“Sahota has a surgeon’s dexterous hands, and the reader senses his confidence. … A plot-packed, propulsive story.”

From Caoilinn Hughes’s review

Viking | $29

SPIRAL AND OTHER STORIES Aidan Koch

The lush, sparsely worded work of this award-winning graphic novelist less resembles anything recognizably “comic book” than it does a sort of dreamlike oasis of art. Her latest piece of masterful minimalism, constructed from sensuous washes of watercolor, pencil, crayon and collage, pulses with bright pigment and tender melancholy.

“Many of these pages are purely abstract, but when Koch draws details, it’s in startlingly specific and consistent contours that give these stories a breadth of character as well as depiction.”

The Pediatric Hospital Medicine (PHM) Fellowship Directors, recent fellowship graduates, and senior leaders in PHM have long identified training in scholarly activities as a key educational priority for fellowship training programs. We led a 2-day conference funded by the Agency for Healthcare Research and Quality to develop scholarship core competencies for PHM fellows. Participants included fellowship directors, national experts in PHM research, and representatives from key stakeholder organizations. Through engagement in large group presentations and small group iterative feedback and editing, participants created and refined a set of scholarship core competencies. After the conference, goals and objectives were edited and harmonized by conference leaders incorporating feedback from conference participants. Core competency development included 7 domains: (1) study design and execution, (2) data management, (3) principles of analytics, (4) critical appraisal of the medical literature, (5) ethics and responsible conduct of research, (6) peer review, dissemination, and funding, and (7) professionalism and leadership. Specific objectives for each goal were further organized into 3 levels to indicate core skills for all fellowship trainees (level 1), specialized and specific skills determined by fellow scholarly focus (level 2), and advanced skills for fellows interested in a clinical investigator career path (level 3). These newly developed scholarship core competencies provide a foundation for curricular development and implementation to ensure that the field continues to expand academically, given the 2-year training period and variable infrastructure across programs.

Pediatric Hospital Medicine (PHM) is the fastest-growing subspecialty in pediatrics, with 1 of every 12 residency graduates entering the field. 1 – 5   Fellowship programs in PHM have existed since the late 1990s, rapidly growing and evolving over time to meet the needs of the trainees and the field. 6 – 9   In recognition of the specific skill set required for its practice, PHM was designated a subspecialty by the American Board of Medical Specialties with a 2-year fellowship program in 2016. 10   Concurrent with PHM subspecialty recognition, hospitals have seen major changes in the organization, delivery, and financing of health care, signaling the need to provide better care with better value. 11 , 12   Our young field, like others before, faces the challenge of developing academic scholars to drive innovation in research, including advances in the safety and efficiency of health care delivery, the identification and mitigation of health care disparities, and the discovery, implementation, and dissemination of best practices. A strong core curriculum in scholarly activities for fellows is critical for the field of PHM to expand academically, which, in turn, will propel us forward in providing the highest quality of care for hospitalized children.

There are several major challenges to training PHM fellows in scholarly activities. First, a 2-year fellowship provides less time for research training than traditional 3-year fellowships in other pediatric subspecialties. In the 2-year curricular framework, just one-third of the time is dedicated to scholarly pursuits. 7 , 9   In addition, PHM fellowship program graduates had an identified need for further research skill training. 13 – 15   A standardized and efficient training approach is thus necessary to ensure fellows gain relevant and meaningful research skills. Second, PHM is a new subspecialty and one that, in contrast to other pediatric subspecialties, includes fellowship training programs at both community hospitals and University and Children’s Hospitals. Thus, some fellowship programs, particularly those in community settings, have limited program, division, or even institutional infrastructure and mentorship to conduct scholarly activities and are led by program directors with limited formal research training. Finally, fellowship programs lack objectives for a comprehensive curriculum in scholarly activities and thus struggle to ensure fellows gain the necessary skills to conduct scholarly projects.

To address these concerns, the Council of PHM Fellowship Directors partnered with researchers from the Pediatric Research in Inpatient Settings (PRIS) Network ( www.prisnetwork.org ) to create core competencies for PHM fellow scholarship. The purpose of this article is to describe the development of fellowship goals and objectives for scholarly activities in PHM and to further delineate advanced skills for fellows pursuing careers as physician-scientists.

A 2-day conference was held in April 2019 in Cincinnati, Ohio. The conference was developed and implemented by a planning group composed of fellowship directors with experience in educational theory and scholarship and researchers with diverse expertise in methods and applications of clinical, health services, and translational research, as well as implementation science. The members of this planning group included representatives of the PRIS Network, the Council on Pediatric Subspecialties, the Association of Pediatric Program Directors, the American Board of Pediatrics (ABP) sub-board for PHM, and the Executive Council of the PHM Fellowship Directors.

All existing PHM fellowships were invited to send 1 representative to the conference. PHM fellowship leaders from 40 fellowship programs participated in the conference, representing 83% of actively recruiting programs at the time. Participants also included nationally recognized and grant-funded PHM researchers. In addition, representatives of the 3 major medical societies in our field attended, including the American Academy of Pediatrics Section of Hospital Medicine, the Academic Pediatric Association Hospital Medicine Special Interest Group, and the Society of Hospital Medicine Pediatrics Special Interest Group, as well as representatives from the ABP sub-board, the Association of Pediatric Program Directors, the Council on Pediatric Subspecialties, Children’s Hospital Association, and the PRIS Network. Participants are listed in Supplemental Table 3 .

In preparation for the conference, the planning group reviewed and compiled the national standards for scholarship from the ABP, the Accreditation Council for Graduate Medical Education (ACGME), and the Clinical and Translation Science Awards Program. 16 – 19   Additional scholarly activity requirements from pediatric critical care, pediatric emergency medicine, and the Federation of Pediatric Organizations Policy Statement on Pediatric Fellowship Training were reviewed. 20 – 22   This review of national standards resulted in a comprehensive list that was edited to remove duplicate topics. Next, the planning group completed iterative edits to reach a consensus draft of PHM-specific scholarship goals and objectives. Before the conference, the objectives were arranged into 6 domains: research design, data management, statistical analysis, clinical epidemiology, scientific communications, and responsible conduct of research.

At the conference, the planning group presented an orientation to the 6 domains and a review of educational processes for the development of competencies, goals, and objectives. This review included specific knowledge sharing related to the differences between goals and objectives, the key components of writing effective objectives, and the relationship between competencies, milestones, and entrustable professional activities. Participants were then divided into 6 small groups with at least 1 experienced PHM physician-scientist faculty and at least 1 PHM fellowship program director with advanced education knowledge per group. Each group was assigned a primary and secondary domain from the 6 domains. For the primary domain, the group reviewed the draft goals and objectives and suggested the addition, subtraction, and revision of goals and objectives to align with the expected competencies of PHM fellowship graduates. After this initial review and editing, groups were asked to review and edit a second domain. Ultimately, this configuration allowed for a double review of each domain to reconcile diverging viewpoints and ensure the development of rigorous and comprehensive training goals and objectives. At the conclusion of this small group work, the larger group was reconvened. Each small group then reported on their domains, and facilitators led a large-group discussion to address points of controversy and reach a final consensus around the goals and objectives for each of the 6 domains.

After the conference, the planning group incorporated feedback provided by the conference participants. The 6 initial domains were refined into 7 final domains, each with a specific goal. To account for the many areas of scholarship within PHM and, consequently, the need for broad as well as discrete methodologic knowledge, specific objectives for each goal were further organized into 3 levels. Level 1 objectives indicate core skills expected of all PHM fellows, level 2 objectives represent specialized skills specific to the focus of a fellow’s scholarly work, and level 3 objectives are more advanced objectives specific to fellows interested in a physician-scientist path. Of note, many level 3 objectives are anticipated to require additional time beyond the standard 2-year PHM ACGME fellowship. A final, expert review by the PRIS Network leadership and PHM fellowship program directors then occurred to reconcile any remaining uncertainties. Figure 1 provides an overview of the entire process of developing these scholarship core competencies.

Based on expert review, iterative feedback, and refinement, the initial 6 domains yielded 7 final domains and corresponding goals representing the comprehensive scholarship core competencies expected of PHM fellowship graduates: (1) study design and execution, (2) data management, (3) principles of analytics, (4) critical appraisal of the medical literature, (5) ethics and responsible conduct of research, (6) peer review, dissemination, and funding, and (7) professionalism and leadership ( Tables 1 and 2 ). Each goal is presented with corresponding objectives, including levels 1, 2, and 3 objectives to represent the core objectives expected of all PHM fellows (1), specialized objectives specific to the focus of the fellow’s scholarly work (2), and more advanced objectives for fellows pursuing a physician-scientist path (3).

Scholarship Core Competency Areas and Goals

We present scholarship core competencies for PHM fellows as a tool to advance our training programs and the field of PHM and to complement the clinical core competencies that already exist. We gathered PHM experts from research and education to define the essential scholarship skills that all fellowship graduates should have to conduct scholarship, which will improve outcomes for hospitalized children. Because of the uniquely shorter training period for PHM, we further delineated advanced research competencies trainees interested in physician-scientist careers would need.

We expect the creation and implementation of these scholarship core competencies to serve as the basis for the development of curricula. We anticipate that these competencies will additionally assist programs and fellows in identifying the scholarship knowledge and skills that trainees can expect to accrue during fellowship. Many PHM fellowship programs are located within small-to-medium hospital systems. Such programs may not have the resources of a large academic institution, or their faculty may lack the time and experience needed to mentor fellows in scholarly activities. Content areas frequently lacking from individual program curricula could benefit from national or regional curricula, to provide support to overcome local research and resource infrastructure gaps. Many resources have been in evolution to provide this support over the last decade in our growing field, including content at the annual PHM Conference and PHM Fellows Conference. The development of these competencies provides a framework for program directors to link resources and activities with discrete outcomes and identify continued gaps. With this in mind, the Research Subcommittee of the Council of PHM Fellowship Directors took the objectives that were most challenging for all programs to meet individually and created a recurring webinar series that not only addresses the content gaps but also provides fellows with exposure to researchers in the field. This series has included 4 to 6 topics per year open to all PHM fellows, allowing programs to consistently provide access to education in core scholarly areas, regardless of individual institutional resources. Topics covered have included survey design, quality improvement, qualitative research, databases for research, scientific meeting abstract writing, manuscript writing, and responding to peer reviews. The series has been well received by fellows and program directors and will continue to be enhanced to meet the needs of our fellows nationally. This approach to sharing educational materials nationally has been notably helpful in our young field, in which many fellowship directors and faculty did not complete the fellowship themselves yet are charged with supervising fellow scholarly activity. The Council of PHM Fellowship Directors has also started developing a faculty development curriculum around scholarship mentorship.

In addition to fostering curriculum development, the use of standard goals and objectives provides an opportunity for more consistent evaluation of individual fellows. Programs may benefit from utilizing the standardized research goals and objectives to create evaluation methods to assess fellow competency in scholarly activities. The goals and objectives can also serve as a tool for fellow self-assessment and can aid Scholarship Oversight Committee members in the evaluation of fellows’ scholarly progress.

During the development of the goals and objectives, it was clear that there were core research skills that all fellows should be expected to gain, and that there were additional skills those seeking careers as physician-scientists would require. This recognition led to the creation of tiered objectives in which level 3 objectives represent advanced methods and skills. The training necessary to meet these advanced objectives may require individualized curriculum and time beyond the standard 2-year PHM fellowship, such as the addition of a third year or a master’s degree program.

Although we focused on defining scholarship core competencies for PHM fellows with the goal of improving the health of children, we also believe these standardized goals and objectives can serve as a model for many other medical and surgical specialties and subspecialties. Our rigorous approach began with a review of the literature and the existing resources, most of which were from general medical organizations. We then added to and refined these compiled standards using real-life experiences from a wide variety of research and fellowship training experts who have recognized knowledge in research and research mentorship. Based on the rigor with which we developed these scholarship core competencies, we believe other specialties and subspecialties can feel confident utilizing them within their own programs.

We have presented our collaborative approach to developing scholarship core competencies for PHM fellows in partnership with a variety of national stakeholders. We present goals and objectives to serve as the standard for scholarship in PHM programs nationally while also allowing for curricular content development that can ideally be accessed by all fellows. Our focus was largely on research skills outside of medical education and quality improvement given PHM fellowship program director identified gaps in providing core knowledge in more traditional research skills. Additionally, there has been ongoing work by the Council of PHM Fellowship Directors to develop specific educational and quality improvement goals and objectives. However, there is an overlap in skills presented within these goals and objectives that fellows can apply to educational or quality improvement projects. Future work could endeavor to create a scholarship timeline to aid fellows and fellowship leaders in developing and implementing scholarly projects during a 2-year fellowship. Lastly, these standard goals and objectives will allow for the creation and validation of more objective- and competency-based assessments of fellows and evaluation of scholarship curricula. Of course, because training environments and requirements are constantly in evolution, in particular, because the ACGME is currently revising Pediatric Residency training requirements that may impact PHM fellowship training, these competencies should be revisited and revised as necessary.

The scholarship goals and objectives emphasize the need for research training in several areas of focus, including epidemiology, health services research, clinical trials in complex health systems, and improvement research, among others. We expect research training in PHM fellowships to produce the next generation of expert scholars and physician-scientists who will be equipped to meet new challenges in pediatric hospital medicine and improve the care and outcomes of hospitalized children.

Brought to you by Book Marks , Lit Hub’s home for book reviews.

1. This Strange Eventful History by Claire Messud (W. W. Norton & Company)

14 Rave • 2 Positive Read an interview with Claire Messud here

“This monumental novel, which is a work of salvage and salvation … Quilted from scraps of memory treasured in the author’s attic for decades … Regardless of how much Messud may have drawn from biographical details, though, this novel grips our interest only because of how expertly she shapes these incidents for dramatic effect … A novel of such cavernous depth, such relentless exploration, that it can’t help but make one realize how much we know and how little we confess about our own families. I strove to withhold judgment, to exercise a little skeptical decorum, but I couldn’t help finishing each chapter in a flush of awe.”

–Ron Charles ( The Washington Post )

2. All Fours by Miranda July (Riverhead)

7 Rave • 3 Positive • 1 Mixed

“About the binary of heterosexual love and the claustrophobia inherent in being a mother in a heteronormative family. More broadly, it’s a book about straddling two worlds … In a move that rejects the traditional arc of the hero’s journey, she never even leaves California. But transformation happens anyway. The narrator rediscovers herself not by driving across state lines, but by standing a shadow’s length away.”

–Jenessa Abrams ( The Los Angeles Review of Books )

3. Blue Ruin by Hari Kunzru (Knopf)

6 Rave • 2 Positive • 1 Pan Read an excerpt from Blue Ruin here

“…a lively, ever-intensifying story as Jay weaves in discussions of race, immigration, work, and what it means to earn a living. It’s a darkly ironic tale of two bubbles—an art world divorced from economic reality and a Covid era that segregated us from society. A dark, smart, provocative tale of the perils of art making.”

1. Challenger: A True Story of Heroism and Disaster on the Edge of Space by Adam  Higginbotham (Avid Reader Press)

“Adam Higginbotham provides the most definitive account of the explosion that took the lives of the seven-person crew. He also meticulously explores the missteps and negligence that allowed the tragedy to occur … The pace is so brisk that readers will be surprised when they realize the vivid account of the Challenger launch doesn’t occur until well after halfway through the book … Compelling, comprehensive.”

–Andrew DeMillo ( Associated Press )

2. Skies of Thunder: The Deadly World War II Mission Over the Roof of the World by Caroline  Alexander (Viking)

3 Rave • 3 Positive • 1 Mixed

“Alexander casts her story as an ‘epic,’ yet it is one in which the actors suffer like Job more often than they fight like Achilles. There are stirring episodes of British sang-froid, ‘American-style glamour’ and remarkable courage among the region’s remote tribal peoples, but it is perseverance that assumes heroic proportions … Alexander adroitly explicates technical concepts—flight mechanics, de-icing, night vision—but is at her best rendering pilots’ fear … Epic.”

–Elizabeth D. Samet ( The New York Times Book Review )

3. Rebel Girl: My Life as a Feminist Punk by Kathleen Hanna (Ecco)

3 Rave • 3 Positive

“Packed with harrowing stories and illuminating revelations … Utilizing a voice that’s often bitingly funny but never insincere, Hanna proves a captivating narrator.”

–Zach Ruskin ( The San Francisco Chronicle )
