Why create a concept map.
A concept map is a visualization of key idea in your research and the relationships between them. To create a concept map, pick out the main concepts of your topic and brainstorm everything you know about them, drawing shapes around your concepts and clustering the shapes in a way that's meaningful to you. How can this help?
You are here, structuring your ideas: creating a literature map.
It is important to have a plan of the areas to be discussed, using this to indicated how these will link together. In the overall structure of the literature review, there should be a logical flow of ideas and within each paragraph there should be a clear theme, around which related ideas are explored and developed. A literature map can be useful for this purpose as it enables you to create a visual representation of the themes and how they could relate to one another.
A literature map (Cresswell, 2011) is a two dimensional diagrammatic representation of information where links are made between concepts by drawing arrows (which could be annotated to define the nature of these links). Constructing a literature map helps you to:
Your map can then be used as a plan for your literature review.
As well has helping you to organise the literature for your review, a literature map can be used to help you analyse the information in a particular journal article, supporting the exploration of strengths and weaknesses of the methodology and the resultant findings and enabling you to explore how key themes and concepts in the article link together.
It is important to represent the different views and any conflicting research findings that exist in the literature (Newby, 2014). There is a danger of selective referencing, only including literature that supports your own beliefs and findings, disregarding alternative views. This should be avoided as it is based on the assumption that your views are the correct ones, and it is possible that you could miss key ideas and findings that could take your research in new and exciting directions.
1. Purpose and Scope
To help you develop a literature review, gather information on existing research, sub-topics, relevant research, and overlaps. Note initial thoughts on the topic - a mind map or list might be helpful - and avoid unfocused reading, collecting irrelevant content. A literature review serves to place your research within the context of existing knowledge. It demonstrates your understanding of the field and identifies gaps that your research aims to fill. This helps in justifying the relevance and necessity of your study.
To avoid over-reading, set a target word count for each section and limit reading time. Plan backwards from the deadline and move on to other parts of the investigation. Read major texts and explore up-to-date research. Check reference lists and citation indexes for common standard texts. Be guided by research questions and refocus on your topic when needed. Stop reading if you find similar viewpoints or if you're going off topic.
You can use a "Synthesis Matrix" to keep track of your reading notes. This concept map helps you to provide a summary of the literature and its connections is produced as a result of this study. Utilizing referencing software like RefWorks to obtain citations, you can construct the framework for composing your literature evaluation.
2. Source Selection
Focus on searching for academically authoritative texts such as academic books, journals, research reports, and government publications. These sources are critical for ensuring the credibility and reliability of your review.
3. Thematic Analysis
Instead of merely summarizing sources, identify and discuss key themes that emerge from the literature. This involves interpreting and evaluating how different authors have tackled similar issues and how their findings relate to your research.
4. Critical Evaluation
Adopt a critical attitude towards the sources you review. Scrutinize, question, and dissect the material to ensure that your review is not just descriptive but analytical. This helps in highlighting the significance of various sources and their relevance to your research.
Each work's critical assessment should take into account:
Provenance: What qualifications does the author have? Are the author's claims backed up by proof, such as first-hand accounts from history, case studies, stories, statistics, and current scientific discoveries? Methodology: Were the strategies employed to locate, collect, and evaluate the data suitable for tackling the study question? Was the sample size suitable? Were the findings properly reported and interpreted? Objectivity : Is the author's viewpoint impartial or biased? Does the author's thesis get supported by evidence that refutes it, or does it ignore certain important facts? Persuasiveness: Which of the author's arguments is the strongest or weakest in terms of persuasiveness? Value: Are the author's claims and deductions believable? Does the study ultimately advance our understanding of the issue in any meaningful way?
5. Categorization
Organize your literature review by grouping sources into categories based on themes, relevance to research questions, theoretical paradigms, or chronology. This helps in presenting your findings in a structured manner.
6. Source Validity
Ensure that the sources you include are valid and reliable. Classic texts may retain their authority over time, but for fields that evolve rapidly, prioritize the most recent research. Always check the credibility of the authors and the impact of their work in the field.
7. Synthesis and Findings
Synthesize the information from various sources to draw conclusions about the current state of knowledge. Identify trends, controversies, and gaps in the literature. Relate your findings to your research questions and suggest future directions for research.

Literature mapping is a way of discovering scholarly articles by exploring connections between publications.
Similar articles are often linked by citations, authors, funders, keywords, and other metadata. These connections can be explored manually in a database such as Scopus or by the use of free browser-based tools such as Connected Papers , L itMaps , and Open Knowledge Maps .
The following is an introduction to these four methods.
Literature mapping in 30 minutes (slides).
A literature review is a summary of the existing knowledge and research on a particular subject. by identifying gaps in the literature, it provides a foundation for future research. as such, it’s a crucial first step in any research project..
A literature review serves several purposes:
Looking at existing examples of literature reviews is beneficial to get a clear understanding of what they entail. Find examples of a literature review by using an academic search engine (e.g. Google Scholar). As a starting point, search for your keyword or topic along with the term "literature review".
Identify the research question or topic, making it as narrow as possible. In this example of a literature review, we review the anxiolytic (anti-anxiety) activity of Piper methysticum , or Kava .
Let's walk through the steps in the process with this literature review example.
First, identify the research question or topic, making it as narrow as possible. In this literature review example, we're examining the effects of urbanization on the migration of birds.
Searching for relevant studies is arguably the most important aspect of the literature review.
Start by identifying keywords and phrases related to the topic and use them to search academic journals and databases ( Google Scholar , BASE , PubMed , etc.). For our example, you might start with "the effects of urbanization on bird migration", but after researching the field, discover that other terms like "avian migration" and "avian populations" are more commonly used.
Search for your keywords in Litmaps to find some initial articles to explore the field from. You can then use Litmaps to find additinal sources and curate a whole library of literature on your topic.
Search for your keywords in Litmaps, and select a starting article. This will return a visualization containing suggestions for relevant articles on your literature review topic. Review these to start curating your library.
Evaluate the relevance and quality of the sources found by reading abstracts of the most relevant articles. Additionally, consider the publication venue, year of publication and other salient measures to identify the reliability and relevance of the source.
Take notes on the key findings, methodologies, and theoretical frameworks used in the studies.
Use a research-friendly note-taking software, like Obsidian , that provide #tags to keep track of key concepts.
Organize the literature according to themes, subtopics, or categories, which will help outline the layout of the literature review.
Tag keywords using a tool like Obsidian to help organize papers into subtopics for the review.
Summarize and synthesize the findings from the sources analyzed. Start with an introduction that defines the research question, followed by the themes, subtopics, or categories identified. After that, provide a discussion or conclusion that addresses any gaps in the literature to motivate future research. Lastly, edit and revise your review to ensure it is well-structured, clear, and concise. The example below is from a review paper, which includes a table comparing the different sources evaluated. Such tables can be useful if you are conducting a comprehensive review.
If you're conducting a comprehensive review, you can include a table of sources reviewed in your process, like the one above from this publication .
Lastly, cite and reference the sources used in the literature review. Consider any referencing style requirements of the institution or journal you're submitting to. APA is the most common. However, you may need to familiarize yourself with other citation styles such as MLA, Chicago, or MHRA depending on your venue. See the image below for a literature review example APA of references. To cite references you've saved in Litmaps, you can move your saved articles from Litmaps to a reference manager (i.e. Zotero, Mendeley, EndNote, etc.) and then export their bibliography from there. Here's how to export articles from Litmaps.
Use a reference manager tool like Zotero to easily export which makes them easy to manage, like in this APA literature review example.
A successful literature review tells a brief story about the topic at hand and leaves the reader a clear notion of what has been covered. Most importantly, a literature review addresses any gaps in the field and frames newly presented research. Understand the key steps and look at literature review examples in order to create a high quality review.

We encourage readers to share comments on or suggestions for this section on Twitter, using the hashtag: #how’syourwriting?
This Writer’s Craft instalment is the first in a two-part series that offers strategies for effectively presenting the literature review section of a research manuscript. This piece alerts writers to the importance of not only summarizing what is known but also identifying precisely what is not, in order to explicitly signal the relevance of their research. In this instalment, I will introduce readers to the mapping the gap metaphor, the knowledge claims heuristic, and the need to characterize the gap.
The purpose of the literature review section of a manuscript is not to report what is known about your topic. The purpose is to identify what remains unknown— what academic writing scholar Janet Giltrow has called the ‘knowledge deficit’ — thus establishing the need for your research study [ 1 ]. In an earlier Writer’s Craft instalment, the Problem-Gap-Hook heuristic was introduced as a way of opening your paper with a clear statement of the problem that your work grapples with, the gap in our current knowledge about that problem, and the reason the gap matters [ 2 ]. This article explains how to use the literature review section of your paper to build and characterize the Gap claim in your Problem-Gap-Hook. The metaphor of ‘mapping the gap’ is a way of thinking about how to select and arrange your review of the existing literature so that readers can recognize why your research needed to be done, and why its results constitute a meaningful advance on what was already known about the topic.
Many writers have learned that the literature review should describe what is known. The trouble with this approach is that it can produce a laundry list of facts-in-the-world that does not persuade the reader that the current study is a necessary next step. Instead, think of your literature review as painting in a map of your research domain: as you review existing knowledge, you are painting in sections of the map, but your goal is not to end with the whole map fully painted. That would mean there is nothing more we need to know about the topic, and that leaves no room for your research. What you want to end up with is a map in which painted sections surround and emphasize a white space, a gap in what is known that matters. Conceptualizing your literature review this way helps to ensure that it achieves its dual goal: of presenting what is known and pointing out what is not—the latter of these goals is necessary for your literature review to establish the necessity and importance of the research you are about to describe in the methods section which will immediately follow the literature review.
To a novice researcher or graduate student, this may seem counterintuitive. Hopefully you have invested significant time in reading the existing literature, and you are understandably keen to demonstrate that you’ve read everything ever published about your topic! Be careful, though, not to use the literature review section to regurgitate all of your reading in manuscript form. For one thing, it creates a laundry list of facts that makes for horrible reading. But there are three other reasons for avoiding this approach. First, you don’t have the space. In published medical education research papers, the literature review is quite short, ranging from a few paragraphs to a few pages, so you can’t summarize everything you’ve read. Second, you’re preaching to the converted. If you approach your paper as a contribution to an ongoing scholarly conversation,[ 2 ] then your literature review should summarize just the aspects of that conversation that are required to situate your conversational turn as informed and relevant. Third, the key to relevance is to point to a gap in what is known. To do so, you summarize what is known for the express purpose of identifying what is not known . Seen this way, the literature review should exert a gravitational pull on the reader, leading them inexorably to the white space on the map of knowledge you’ve painted for them. That white space is the space that your research fills.
To help writers move beyond the laundry list, the notion of ‘knowledge claims’ can be useful. A knowledge claim is a way of presenting the growing understanding of the community of researchers who have been exploring your topic. These are not disembodied facts, but rather incremental insights that some in the field may agree with and some may not, depending on their different methodological and disciplinary approaches to the topic. Treating the literature review as a story of the knowledge claims being made by researchers in the field can help writers with one of the most sophisticated aspects of a literature review—locating the knowledge being reviewed. Where does it come from? What is debated? How do different methodologies influence the knowledge being accumulated? And so on.
Consider this example of the knowledge claims (KC), Gap and Hook for the literature review section of a research paper on distributed healthcare teamwork:
KC: We know that poor team communication can cause errors. KC: And we know that team training can be effective in improving team communication. KC: This knowledge has prompted a push to incorporate teamwork training principles into health professions education curricula. KC: However, most of what we know about team training research has come from research with co-located teams—i. e., teams whose members work together in time and space. Gap: Little is known about how teamwork training principles would apply in distributed teams, whose members work asynchronously and are spread across different locations. Hook: Given that much healthcare teamwork is distributed rather than co-located, our curricula will be severely lacking until we create refined teamwork training principles that reflect distributed as well as co-located work contexts.
The ‘We know that …’ structure illustrated in this example is a template for helping you draft and organize. In your final version, your knowledge claims will be expressed with more sophistication. For instance, ‘We know that poor team communication can cause errors’ will become something like ‘Over a decade of patient safety research has demonstrated that poor team communication is the dominant cause of medical errors.’ This simple template of knowledge claims, though, provides an outline for the paragraphs in your literature review, each of which will provide detailed evidence to illustrate a knowledge claim. Using this approach, the order of the paragraphs in the literature review is strategic and persuasive, leading the reader to the gap claim that positions the relevance of the current study. To expand your vocabulary for creating such knowledge claims, linking them logically and positioning yourself amid them, I highly recommend Graff and Birkenstein’s little handbook of ‘templates’ [ 3 ].
As you organize your knowledge claims, you will also want to consider whether you are trying to map the gap in a well-studied field, or a relatively understudied one. The rhetorical challenge is different in each case. In a well-studied field, like professionalism in medical education, you must make a strong, explicit case for the existence of a gap. Readers may come to your paper tired of hearing about this topic and tempted to think we can’t possibly need more knowledge about it. Listing the knowledge claims can help you organize them most effectively and determine which pieces of knowledge may be unnecessary to map the white space your research attempts to fill. This does not mean that you leave out relevant information: your literature review must still be accurate. But, since you will not be able to include everything, selecting carefully among the possible knowledge claims is essential to producing a coherent, well-argued literature review.
Once you’ve identified the gap, your literature review must characterize it. What kind of gap have you found? There are many ways to characterize a gap, but some of the more common include:
To characterize the kind of gap, you need to know the literature thoroughly. That means more than understanding each paper individually; you also need to be placing each paper in relation to others. This may require changing your note-taking technique while you’re reading; take notes on what each paper contributes to knowledge, but also on how it relates to other papers you’ve read, and what it suggests about the kind of gap that is emerging.
In summary, think of your literature review as mapping the gap rather than simply summarizing the known. And pay attention to characterizing the kind of gap you’ve mapped. This strategy can help to make your literature review into a compelling argument rather than a list of facts. It can remind you of the danger of describing so fully what is known that the reader is left with the sense that there is no pressing need to know more. And it can help you to establish a coherence between the kind of gap you’ve identified and the study methodology you will use to fill it.
