- Steps in Conducting a Literature Review
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.

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.

Conducting a literature review: why do a literature review, why do a literature review.
- How To Find "The Literature"
- Found it -- Now What?
Besides the obvious reason for students -- because it is assigned! -- a literature review helps you explore the research that has come before you, to see how your research question has (or has not) already been addressed.
You identify:
- core research in the field
- experts in the subject area
- methodology you may want to use (or avoid)
- gaps in knowledge -- or where your research would fit in
It Also Helps You:
- Publish and share your findings
- Justify requests for grants and other funding
- Identify best practices to inform practice
- Set wider context for a program evaluation
- Compile information to support community organizing

5 Reasons the Literature Review Is Crucial to Your Paper
3-minute read
- 8th November 2016
People often treat writing the literature review in an academic paper as a formality. Usually, this means simply listing various studies vaguely related to their work and leaving it at that.
But this overlooks how important the literature review is to a well-written experimental report or research paper. As such, we thought we’d take a moment to go over what a literature review should do and why you should give it the attention it deserves.
What Is a Literature Review?
Common in the social and physical sciences, but also sometimes required in the humanities, a literature review is a summary of past research in your subject area.
Sometimes this is a standalone investigation of how an idea or field of inquiry has developed over time. However, more usually it’s the part of an academic paper, thesis or dissertation that sets out the background against which a study takes place.
There are several reasons why we do this.
Reason #1: To Demonstrate Understanding
In a college paper, you can use a literature review to demonstrate your understanding of the subject matter. This means identifying, summarizing and critically assessing past research that is relevant to your own work.
Reason #2: To Justify Your Research
The literature review also plays a big role in justifying your study and setting your research question . This is because examining past research allows you to identify gaps in the literature, which you can then attempt to fill or address with your own work.

Reason #3: Setting a Theoretical Framework
It can help to think of the literature review as the foundations for your study, since the rest of your work will build upon the ideas and existing research you discuss therein.
A crucial part of this is formulating a theoretical framework , which comprises the concepts and theories that your work is based upon and against which its success will be judged.
Reason #4: Developing a Methodology
Conducting a literature review before beginning research also lets you see how similar studies have been conducted in the past. By examining the strengths and weaknesses of existing research, you can thus make sure you adopt the most appropriate methods, data sources and analytical techniques for your own work.
Reason #5: To Support Your Own Findings
The significance of any results you achieve will depend to some extent on how they compare to those reported in the existing literature. When you come to write up your findings, your literature review will therefore provide a crucial point of reference.
If your results replicate past research, for instance, you can say that your work supports existing theories. If your results are different, though, you’ll need to discuss why and whether the difference is important.

The Research Process
Planning : Before searching for articles or books, brainstorm to develop keywords that better describe your research question.
Searching : While searching, take note of what other keywords are used to describe your topic, and use them to conduct additional searches
♠ Most articles include a keyword section
♠ Key concepts may change names throughout time so make sure to check for variations
Organizing : Start organizing your results by categories/key concepts or any organizing principle that make sense for you . This will help you later when you are ready to analyze your findings
Analyzing : While reading, start making notes of key concepts and commonalities and disagreement among the research articles you find.
♠ Create a spreadsheet to record what articles you are finding useful and why.
♠ Create fields to write summaries of articles or quotes for future citing and paraphrasing .
Writing : Synthesize your findings. Use your own voice to explain to your readers what you learned about the literature on your topic. What are its weaknesses and strengths? What is missing or ignored?
Repeat : At any given time of the process, you can go back to a previous step as necessary.
Advanced Searching
All databases have Help pages that explain the best way to search their product. When doing literature reviews, you will want to take advantage of these features since they can facilitate not only finding the articles that you really need but also controlling the number of results and how relevant they are for your search. The most common features available in the advanced search option of databases and library online catalogs are:
- Boolean Searching (AND, OR, NOT): Allows you to connect search terms in a way that can either limit or expand your search results
- Proximity Searching (N/# or W/#): Allows you to search for two or more words that occur within a specified number of words (or fewer) of each other in the database
- Limiters/Filters : These are options that let you control what type of document you want to search: article type, date, language, publication, etc.
- Question mark (?) or a pound sign (#) for wildcard: Used for retrieving alternate spellings of a word: colo?r will retrieve both the American spelling "color" as well as the British spelling "colour."
- Asterisk (*) for truncation: Used for retrieving multiple forms of a word: comput* retrieves computer, computers, computing, etc.

- ProQuest Database Search Tips Tips for searching another platform that hosts library databases
There is no magic number regarding how many sources you are going to need for your literature review; it all depends on the topic and what type of the literature review you are doing:
► Are you working on an emerging topic? You are not likely to find many sources, which is good because you are trying to prove that this is a topic that needs more research. But, it is not enough to say that you found few or no articles on your topic in your field. You need to look broadly to other disciplines (also known as triangulation ) to see if your research topic has been studied from other perspectives as a way to validate the uniqueness of your research question.
► Are you working on something that has been studied extensively? Then you are going to find many sources and you will want to limit how far back you want to look. Use limiters to eliminate research that may be dated and opt to search for resources published within the last 5-10 years.

Disclaimer!!
Conducting a literature review is usually recursive, meaning that somewhere along the way, you'll find yourself repeating steps out-of-order.
That is actually a good sign.
Reviewing the research should lead to more research questions and those questions will likely lead you to either revise your initial research question or go back and find more literature related to a more specific aspect of your research question.
Your literature review should be guided by a central research question. Remember, it is not a collection of loosely related studies in a field but instead 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.
How many studies do you need to look at? How comprehensive should it be? How many years should it cover?
Tip: This may depend on your assignment. How many sources does the assignment require?
Make a list of the databases you will search. Remember to include comprehensive databases such as WorldCat and Dissertations & Theses, if you need to.
Where to find databases:
- Find Databases by Subject UWF Databases categorized by discipline
- Find Databases via Research Guides Librarians create research guides for all of the disciplines on campus! Take advantage of their expertise and see what discipline-specific search strategies they recommend!
- Review the abstracts of research studies carefully. This will save you time.
- Write down the searches you conduct in each database so that you may duplicate them if you need to later (or avoid dead-end searches that you'd forgotten you'd already tried).
- Use the bibliographies and references of research studies you find to locate others.
- Ask your professor or a scholar in the field if you are missing any key works in the field.
- Use RefWorks to keep track of your research citations. See the RefWorks Tutorial if you need help.
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:
- Again, review the abstracts carefully.
- Keep careful notes so that you may track your thought processes during the research process.

What is a Literature Review?
Description.
A literature review, also called a review article or review of literature, surveys the existing research on a topic. The term "literature" in this context refers to published research or scholarship in a particular discipline, rather than "fiction" (like American Literature) or an individual work of literature. In general, literature reviews are most common in the sciences and social sciences.
Literature reviews may be written as standalone works, or as part of a scholarly article or research paper. In either case, the purpose of the review is to summarize and synthesize the key scholarly work that has already been done on the topic at hand. The literature review may also include some analysis and interpretation. A literature review is not a summary of every piece of scholarly research on a topic.
Why are literature reviews useful?
Literature reviews can be very helpful for newer researchers or those unfamiliar with a field by synthesizing the existing research on a given topic, providing the reader with connections and relationships among previous scholarship. Reviews can also be useful to veteran researchers by identifying potentials gaps in the research or steering future research questions toward unexplored areas. If a literature review is part of a scholarly article, it should include an explanation of how the current article adds to the conversation. (From: https://researchguides.drake.edu/englit/criticism)
How is a literature review different from a research article?
Research articles: "are empirical articles that describe one or several related studies on a specific, quantitative, testable research question....they are typically organized into four text sections: Introduction, Methods, Results, Discussion." Source: https://psych.uw.edu/storage/writing_center/litrev.pdf)
Steps for Writing a Literature Review
1. Identify and define the topic that you will be reviewing.
The topic, which is commonly a research question (or problem) of some kind, needs to be identified and defined as clearly as possible. You need to have an idea of what you will be reviewing in order to effectively search for references and to write a coherent summary of the research on it. At this stage it can be helpful to write down a description of the research question, area, or topic that you will be reviewing, as well as to identify any keywords that you will be using to search for relevant research.
2. Conduct a Literature Search
Use a range of keywords to search databases such as PsycINFO and any others that may contain relevant articles. You should focus on peer-reviewed, scholarly articles . In SuperSearch and most databases, you may find it helpful to select the Advanced Search mode and include "literature review" or "review of the literature" in addition to your other search terms. Published books may also be helpful, but keep in mind that peer-reviewed articles are widely considered to be the “gold standard” of scientific research. Read through titles and abstracts, select and obtain articles (that is, download, copy, or print them out), and save your searches as needed. Most of the databases you will need are linked to from the Cowles Library Psychology Research guide .
3. Read through the research that you have found and take notes.
Absorb as much information as you can. Read through the articles and books that you have found, and as you do, take notes. The notes should include anything that will be helpful in advancing your own thinking about the topic and in helping you write the literature review (such as key points, ideas, or even page numbers that index key information). Some references may turn out to be more helpful than others; you may notice patterns or striking contrasts between different sources; and some sources may refer to yet other sources of potential interest. This is often the most time-consuming part of the review process. However, it is also where you get to learn about the topic in great detail. You may want to use a Citation Manager to help you keep track of the citations you have found.
4. Organize your notes and thoughts; create an outline.
At this stage, you are close to writing the review itself. However, it is often helpful to first reflect on all the reading that you have done. What patterns stand out? Do the different sources converge on a consensus? Or not? What unresolved questions still remain? You should look over your notes (it may also be helpful to reorganize them), and as you do, to think about how you will present this research in your literature review. Are you going to summarize or critically evaluate? Are you going to use a chronological or other type of organizational structure? It can also be helpful to create an outline of how your literature review will be structured.
5. Write the literature review itself and edit and revise as needed.
The final stage involves writing. When writing, keep in mind that literature reviews are generally characterized by a summary style in which prior research is described sufficiently to explain critical findings but does not include a high level of detail (if readers want to learn about all the specific details of a study, then they can look up the references that you cite and read the original articles themselves). However, the degree of emphasis that is given to individual studies may vary (more or less detail may be warranted depending on how critical or unique a given study was). After you have written a first draft, you should read it carefully and then edit and revise as needed. You may need to repeat this process more than once. It may be helpful to have another person read through your draft(s) and provide feedback.
6. Incorporate the literature review into your research paper draft. (note: this step is only if you are using the literature review to write a research paper. Many times the literature review is an end unto itself).
After the literature review is complete, you should incorporate it into your research paper (if you are writing the review as one component of a larger paper). Depending on the stage at which your paper is at, this may involve merging your literature review into a partially complete Introduction section, writing the rest of the paper around the literature review, or other processes.

Why and How to Conduct a Literature Review
“Why you or other researchers need a literature review is rarely discussed, or when it is, it is quickly glossed over. With a full understanding about the purpose of a literature review, people are better able to accomplish them,” says Callie M. Rennison , researcher and public affairs professor at the University of Colorado Denver.
When done so successfully, literature reviews are integral to the research process. They can provide justification, context, and credibility for new studies. By writing a literature review, a researcher recognizes strengths that they want to replicate in their own studies and identifies limitations that need to be addressed and overcome. Additionally, reviews put new research topics into perspective by giving them context within the wider area of related research. Conducting a well-written literature review demonstrates understanding of the topic at hand, giving new findings credibility and supporting evidence.
View the infographic to learn why professors from around the country agree that a strong literature review is crucial for the foundation of an authoritative study. Then learn how to write one in nine basic steps, summarized by Rennison, co-author of SAGE textbook Research Methods in Criminal Justice and Criminology .

Surveys Provide Insight Into Three Factors That Encourage Open Data and Science
Over a 10-year period Carol Tenopir of DataONE and her team conducted a global survey of scientists, managers and government workers involved in broad environmental science activities about their willingness to share data and their opinion of the resources available to do so (Tenopir et al., 2011, 2015, 2018, 2020). Comparing the responses over that time shows a general increase in the willingness to share data (and thus engage in Open Science).
Unskilled But Aware: Rethinking The Dunning-Kruger Effect
As a math professor who teaches students to use data to make informed decisions, I am familiar with common mistakes people make when dealing with numbers.

But in a recent paper, my colleagues and I suggest that the mathematical approach used to show this effect may be incorrect.
Maintaining Anonymity In Double-Blind Peer Review During The Age of Artificial Intelligence
The double-blind review process, adopted by many publishers and funding agencies, plays a vital role in maintaining fairness and unbiasedness by concealing the identities of authors and reviewers. However, in the era of artificial intelligence (AI) and big data, a pressing question arises: can an author’s identity be deduced even from an anonymized paper (in cases where the authors do not advertise their submitted article on social media)?
Hype Terms In Research: Words Exaggerating Results Undermine Findings
The claim that academics hype their research is not news. The use of subjective or emotive words that glamorize, publicize, embellish or exaggerate results and promote the merits of studies has been noted for some time and has drawn criticism from researchers themselves. Some argue hyping practices have reached a level where objectivity has been replaced by sensationalism and manufactured excitement. By exaggerating the importance of findings, writers are seen to undermine the impartiality of science, fuel skepticism and alienate readers.

Reviewing literature for research: Doing it the right way
Shital amin poojary.
Department of Dermatology, K J Somaiya Medical College, Mumbai, Maharashtra, India
Jimish Deepak Bagadia
In an era of information overload, it is important to know how to obtain the required information and also to ensure that it is reliable information. Hence, it is essential to understand how to perform a systematic literature search. This article focuses on reliable literature sources and how to make optimum use of these in dermatology and venereology.
INTRODUCTION
A thorough review of literature is not only essential for selecting research topics, but also enables the right applicability of a research project. Most importantly, a good literature search is the cornerstone of practice of evidence based medicine. Today, everything is available at the click of a mouse or at the tip of the fingertips (or the stylus). Google is often the Go-To search website, the supposed answer to all questions in the universe. However, the deluge of information available comes with its own set of problems; how much of it is actually reliable information? How much are the search results that the search string threw up actually relevant? Did we actually find what we were looking for? Lack of a systematic approach can lead to a literature review ending up as a time-consuming and at times frustrating process. Hence, whether it is for research projects, theses/dissertations, case studies/reports or mere wish to obtain information; knowing where to look, and more importantly, how to look, is of prime importance today.
Literature search
Fink has defined research literature review as a “systematic, explicit and reproducible method for identifying, evaluating, and synthesizing the existing body of completed and recorded work produced by researchers, scholars and practitioners.”[ 1 ]
Review of research literature can be summarized into a seven step process: (i) Selecting research questions/purpose of the literature review (ii) Selecting your sources (iii) Choosing search terms (iv) Running your search (v) Applying practical screening criteria (vi) Applying methodological screening criteria/quality appraisal (vii) Synthesizing the results.[ 1 ]
This article will primarily concentrate on refining techniques of literature search.
Sources for literature search are enumerated in Table 1 .
Sources for literature search
PubMed is currently the most widely used among these as it contains over 23 million citations for biomedical literature and has been made available free by National Center for Biotechnology Information (NCBI), U.S. National Library of Medicine. However, the availability of free full text articles depends on the sources. Use of options such as advanced search, medical subject headings (MeSH) terms, free full text, PubMed tutorials, and single citation matcher makes the database extremely user-friendly [ Figure 1 ]. It can also be accessed on the go through mobiles using “PubMed Mobile.” One can also create own account in NCBI to save searches and to use certain PubMed tools.
PubMed home page showing location of different tools which can be used for an efficient literature search
Tips for efficient use of PubMed search:[ 2 , 3 , 4 ]
Use of field and Boolean operators
When one searches using key words, all articles containing the words show up, many of which may not be related to the topic. Hence, the use of operators while searching makes the search more specific and less cumbersome. Operators are of two types: Field operators and Boolean operators, the latter enabling us to combine more than one concept, thereby making the search highly accurate. A few key operators that can be used in PubMed are shown in Tables Tables2 2 and and3 3 and illustrated in Figures Figures2 2 and and3 3 .
Field operators used in PubMed search
Boolean operators used in PubMed search
PubMed search results page showing articles on donovanosis using the field operator [TIAB]; it shows all articles which have the keyword “donovanosis” in either title or abstract of the article
PubMed search using Boolean operators ‘AND’, ‘NOT’; To search for articles on treatment of lepra reaction other than steroids, after clicking the option ‘Advanced search’ on the home page, one can build the search using ‘AND’ option for treatment and ‘NOT’ option for steroids to omit articles on steroid treatment in lepra reaction
Use of medical subject headings terms
These are very specific and standardized terms used by indexers to describe every article in PubMed and are added to the record of every article. A search using MeSH will show all articles about the topic (or keywords), but will not show articles only containing these keywords (these articles may be about an entirely different topic, but still may contain your keywords in another context in any part of the article). This will make your search more specific. Within the topic, specific subheadings can be added to the search builder to refine your search [ Figure 4 ]. For example, MeSH terms for treatment are therapy and therapeutics.
PubMed search using medical subject headings (MeSH) terms for management of gonorrhea. Click on MeSH database ( Figure 1 ) →In the MeSH search box type gonorrhea and click search. Under the MeSH term gonorrhea, there will be a list of subheadings; therapy, prevention and control, click the relevant check boxes and add to search builder →Click on search →All articles on therapy, prevention and control of gonorrhea will be displayed. Below the subheadings, there are two options: (1) Restrict to medical subject headings (MeSH) major topic and (2) do not include MeSH terms found below this term in the MeSH hierarchy. These can be used to further refine the search results so that only articles which are majorly about treatment of gonorrhea will be displayed
Two additional options can be used to further refine MeSH searches. These are located below the subheadings for a MeSH term: (1) Restrict to MeSH major topic; checking this box will retrieve articles which are majorly about the search term and are therefore, more focused and (2) Do not include MeSH terms found below this term in the MeSH hierarchy. This option will again give you more focused articles as it excludes the lower specific terms [ Figure 4 ].
Similar feature is available with Cochrane library (also called MeSH), EMBASE (known as EMTREE) and PsycINFO (Thesaurus of Psychological Index Terms).
Saving your searches
Any search that one has performed can be saved by using the ‘Send to’ option and can be saved as a simple word file [ Figure 5 ]. Alternatively, the ‘Save Search’ button (just below the search box) can be used. However, it is essential to set up an NCBI account and log in to NCBI for this. One can even choose to have E-mail updates of new articles in the topic of interest.
Saving PubMed searches. A simple option is to click on the dropdown box next to ‘Send to’ option and then choose among the options. It can be saved as a text or word file by choosing ‘File’ option. Another option is the “Save search” option below the search box but this will require logging into your National Center for Biotechnology Information account. This however allows you to set up alerts for E-mail updates for new articles
Single citation matcher
This is another important tool that helps to find the genuine original source of a particular research work (when few details are known about the title/author/publication date/place/journal) and cite the reference in the most correct manner [ Figure 6 ].
Single citation matcher: Click on “Single citation matcher” on PubMed Home page. Type available details of the required reference in the boxes to get the required citation
Full text articles
In any search clicking on the link “free full text” (if present) gives you free access to the article. In some instances, though the published article may not be available free, the author manuscript may be available free of charge. Furthermore, PubMed Central articles are available free of charge.
Managing filters
Filters can be used to refine a search according to type of article required or subjects of research. One can specify the type of article required such as clinical trial, reviews, free full text; these options are available on a typical search results page. Further specialized filters are available under “manage filters:” e.g., articles confined to certain age groups (properties option), “Links” to other databases, article specific to particular journals, etc. However, one needs to have an NCBI account and log in to access this option [ Figure 7 ].
Managing filters. Simple filters are available on the ‘search results’ page. One can choose type of article, e.g., clinical trial, reviews etc. Further options are available in the “Manage filters” option, but this requires logging into National Center for Biotechnology Information account
The Cochrane library
Although reviews are available in PubMed, for systematic reviews and meta-analysis, Cochrane library is a much better resource. The Cochrane library is a collection of full length systematic reviews, which can be accessed for free in India, thanks to Indian Council of Medical Research renewing the license up to 2016, benefitting users all over India. It is immensely helpful in finding detailed high quality research work done in a particular field/topic [ Figure 8 ].
Cochrane library is a useful resource for reliable, systematic reviews. One can choose the type of reviews required, including trials
An important tool that must be used while searching for research work is screening. Screening helps to improve the accuracy of search results. It is of two types: (1) Practical: To identify a broad range of potentially useful studies. Examples: Date of publication (last 5 years only; gives you most recent updates), participants or subjects (humans above 18 years), publication language (English only) (2) methodological: To identify best available studies (for example, excluding studies not involving control group or studies with only randomized control trials).
Selecting the right quality of literature is the key to successful research literature review. The quality can be estimated by what is known as “The Evidence Pyramid.” The level of evidence of references obtained from the aforementioned search tools are depicted in Figure 9 . Systematic reviews obtained from Cochrane library constitute level 1 evidence.
Evidence pyramid: Depicting the level of evidence of references obtained from the aforementioned search tools
Thus, a systematic literature review can help not only in setting up the basis of a good research with optimal use of available information, but also in practice of evidence-based medicine.

How to Structure Your Lit Review
A literature review, even when it is within a larger paper, should include an introduction, a main body section, and a conclusion.
In the Introduction Section :
- define your topic and scope
- explain the organization of your lit review
In the Main Section :
- Present the literature you found related to your topic in a clear, organized way
- Compare and contrast the literature
- Identify problems, issues, and debates among scholars on the topic
There are many ways to organize the main section of a literature review. Here are a few ways you could organize this section:
- Chronological - Present a condensed history of the major ideas and developments of a topic over time.
- Thematic - Present the major theories relevant to your topic and how they agree or contrast.
- Methodological - If there are different methods of research on your topic, you can organize your review by grouping the findings of different methodologies. Be sure to compare and contrast these methods (you are setting up an argument for your own methods.)
- Theoretical - Organize your review by the various theories others have developed relevant to the topic, comparing and contrasting the strengths and weaknesses of each.
In the Conclusion Section :
- Summarize your findings in the scholarly literature
- Identify any gaps and explain briefly how you are filling that gap with your own research (if appropriate)
- Explain how your paper/ideas/research relates to the greater scholarly literature and create a transition to the rest of your paper

Why is it important to do a literature review in research?
The importance of scientific communication in the healthcare industry
The Importance and Role of Biostatistics in Clinical Research
“A substantive, thorough, sophisticated literature review is a precondition for doing substantive, thorough, sophisticated research”. Boote and Baile 2005
Authors of manuscripts treat writing a literature review as a routine work or a mere formality. But a seasoned one knows the purpose and importance of a well-written literature review. Since it is one of the basic needs for researches at any level, they have to be done vigilantly. Only then the reader will know that the basics of research have not been neglected.
The aim of any literature review is to summarize and synthesize the arguments and ideas of existing knowledge in a particular field without adding any new contributions. Being built on existing knowledge they help the researcher to even turn the wheels of the topic of research. It is possible only with profound knowledge of what is wrong in the existing findings in detail to overpower them. For other researches, the literature review gives the direction to be headed for its success.
The common perception of literature review and reality:
As per the common belief, literature reviews are only a summary of the sources related to the research. And many authors of scientific manuscripts believe that they are only surveys of what are the researches are done on the chosen topic. But on the contrary, it uses published information from pertinent and relevant sources like
- Scholarly books
- Scientific papers
- Latest studies in the field
- Established school of thoughts
- Relevant articles from renowned scientific journals
and many more for a field of study or theory or a particular problem to do the following:
- Summarize into a brief account of all information
- Synthesize the information by restructuring and reorganizing
- Critical evaluation of a concept or a school of thought or ideas
- Familiarize the authors to the extent of knowledge in the particular field
- Encapsulate
- Compare & contrast
By doing the above on the relevant information, it provides the reader of the scientific manuscript with the following for a better understanding of it:
- It establishes the authors’ in-depth understanding and knowledge of their field subject
- It gives the background of the research
- Portrays the scientific manuscript plan of examining the research result
- Illuminates on how the knowledge has changed within the field
- Highlights what has already been done in a particular field
- Information of the generally accepted facts, emerging and current state of the topic of research
- Identifies the research gap that is still unexplored or under-researched fields
- Demonstrates how the research fits within a larger field of study
- Provides an overview of the sources explored during the research of a particular topic
Importance of literature review in research:
The importance of literature review in scientific manuscripts can be condensed into an analytical feature to enable the multifold reach of its significance. It adds value to the legitimacy of the research in many ways:
- Provides the interpretation of existing literature in light of updated developments in the field to help in establishing the consistency in knowledge and relevancy of existing materials
- It helps in calculating the impact of the latest information in the field by mapping their progress of knowledge.
- It brings out the dialects of contradictions between various thoughts within the field to establish facts
- The research gaps scrutinized initially are further explored to establish the latest facts of theories to add value to the field
- Indicates the current research place in the schema of a particular field
- Provides information for relevancy and coherency to check the research
- Apart from elucidating the continuance of knowledge, it also points out areas that require further investigation and thus aid as a starting point of any future research
- Justifies the research and sets up the research question
- Sets up a theoretical framework comprising the concepts and theories of the research upon which its success can be judged
- Helps to adopt a more appropriate methodology for the research by examining the strengths and weaknesses of existing research in the same field
- Increases the significance of the results by comparing it with the existing literature
- Provides a point of reference by writing the findings in the scientific manuscript
- Helps to get the due credit from the audience for having done the fact-finding and fact-checking mission in the scientific manuscripts
- The more the reference of relevant sources of it could increase more of its trustworthiness with the readers
- Helps to prevent plagiarism by tailoring and uniquely tweaking the scientific manuscript not to repeat other’s original idea
- By preventing plagiarism , it saves the scientific manuscript from rejection and thus also saves a lot of time and money
- Helps to evaluate, condense and synthesize gist in the author’s own words to sharpen the research focus
- Helps to compare and contrast to show the originality and uniqueness of the research than that of the existing other researches
- Rationalizes the need for conducting the particular research in a specified field
- Helps to collect data accurately for allowing any new methodology of research than the existing ones
- Enables the readers of the manuscript to answer the following questions of its readers for its better chances for publication
- What do the researchers know?
- What do they not know?
- Is the scientific manuscript reliable and trustworthy?
- What are the knowledge gaps of the researcher?
22. It helps the readers to identify the following for further reading of the scientific manuscript:
- What has been already established, discredited and accepted in the particular field of research
- Areas of controversy and conflicts among different schools of thought
- Unsolved problems and issues in the connected field of research
- The emerging trends and approaches
- How the research extends, builds upon and leaves behind from the previous research

There are several reasons to conduct a literature review at the beginning of a research project: To familiarize 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.
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.
Examples of literature reviews. Step 1 - Search for relevant literature. Step 2 - Evaluate and select sources. Step 3 - Identify themes, debates, and gaps. Step 4 - Outline your literature review's structure. Step 5 - Write your literature review.
Besides the obvious reason for students -- because it is assigned! -- a literature review helps you explore the research that has come before you, to see how your research question has (or has not) already been addressed. You identify: core research in the field. experts in the subject area. methodology you may want to use (or avoid)
Writing a literature review requires a range of skills to gather, sort, evaluate and summarise peer-reviewed published data into a relevant and informative unbiased narrative. Digital access to research papers, academic texts, review articles, reference databases and public data sets are all sources of information that are available to enrich ...
Reason #3: Setting a Theoretical Framework. It can help to think of the literature review as the foundations for your study, since the rest of your work will build upon the ideas and existing research you discuss therein. A crucial part of this is formulating a theoretical framework, which comprises the concepts and theories that your work is ...
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" )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given ...
A sophisticated literature review (LR) can result in a robust dissertation/thesis by scrutinizing the main problem examined by the academic study; anticipating research hypotheses, methods and results; and maintaining the interest of the audience in how the dissertation/thesis will provide solutions for the current gaps in a particular field.
The main steps in this research process are: Planning: Before searching for articles or books, brainstorm to develop keywords that better describe your research question. Searching: While searching, take note of what other keywords are used to describe your topic, and use them to conduct additional searches. ♠ Most articles include a keyword ...
Conducting a literature review is usually recursive, meaning that somewhere along the way, you'll find yourself repeating steps out-of-order. That is actually a good sign. Reviewing the research should lead to more research questions and those questions will likely lead you to either revise your initial research question or go back and find ...
6. Incorporate the literature review into your research paper draft. (note: this step is only if you are using the literature review to write a research paper. Many times the literature review is an end unto itself). After the literature review is complete, you should incorporate it into your research paper (if you are writing the review as one ...
When done so successfully, literature reviews are integral to the research process. They can provide justification, context, and credibility for new studies. By writing a literature review, a researcher recognizes strengths that they want to replicate in their own studies and identifies limitations that need to be addressed and overcome.
Literature search. Fink has defined research literature review as a "systematic, explicit and reproducible method for identifying, evaluating, and synthesizing the existing body of completed and recorded work produced by researchers, scholars and practitioners."[]Review of research literature can be summarized into a seven step process: (i) Selecting research questions/purpose of the ...
Researchers conduct literature reviews primarily to identify research gaps and unanswered questions (Option B). By critically analyzing existing studies in their field, they can discover where more research is needed. This is a crucial step in formulating a research question or hypothesis for their own study.
A literature review, even when it is within a larger paper, should include an introduction, a main body section, and a conclusion. In the Introduction Section: define your topic and scope; explain the organization of your lit review; In the Main Section: Present the literature you found related to your topic in a clear, organized way
Importance of literature review in research: The importance of literature review in scientific manuscripts can be condensed into an analytical feature to enable the multifold reach of its significance. It adds value to the legitimacy of the research in many ways: Provides the interpretation of existing literature in light of updated ...
Answer: The purpose of a literature review is to gain an understanding of the existing research and debates relevant to a particular topic or area of study, and to present that knowledge in the form of a written report. Conducting a literature review helps you build your knowledge in your field. You'll learn about important concepts, research ...
A literature review is an assessment of research done by scholars and researchers within a particular area of study.. The importance of conducting or performing a quality literature review cannot be overemphasized as it helps to accomplish the following:It aids the researcher in establishing the current knowledge level of the research topicIdentifies areas of controversy in the research ...
An effective approach to conducting a literature review for a research study is to formulate a tentative research question (RQ) before conducting the literature review to guide the literature search. This is because a well-defined RQ helps to narrow down the scope of the search and provides direction for the sort of literature to seek out.
The experiment will be repeated by the researcher using the exact same approach as the published paper. This serves as an illustration of a replication research. Why do replication studies? An attempt is made to confirm the results of a past study with a replication study. Since the replication study often modifies one or more factors from the ...
