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 Structure Your Literature Review

3 options to help structure your chapter.

By: Amy Rommelspacher (PhD) | Reviewer: Dr Eunice Rautenbach | November 2020 (Updated May 2023)

Writing the literature review chapter can seem pretty daunting when you’re piecing together your dissertation or thesis. As  we’ve discussed before , a good literature review needs to achieve a few very important objectives – it should:

• Demonstrate your knowledge of the research topic
• Identify the gaps in the literature and show how your research links to these
• Provide the foundation for your conceptual framework (if you have one)
• Inform your own  methodology and research design

To achieve this, your literature review needs a well-thought-out structure . Get the structure of your literature review chapter wrong and you’ll struggle to achieve these objectives. Don’t worry though – in this post, we’ll look at how to structure your literature review for maximum impact (and marks!).

But wait – is this the right time?

Deciding on the structure of your literature review should come towards the end of the literature review process – after you have collected and digested the literature, but before you start writing the chapter. 

In other words, you need to first develop a rich understanding of the literature before you even attempt to map out a structure. There’s no use trying to develop a structure before you’ve fully wrapped your head around the existing research.

Equally importantly, you need to have a structure in place before you start writing , or your literature review will most likely end up a rambling, disjointed mess. 

Importantly, don’t feel that once you’ve defined a structure you can’t iterate on it. It’s perfectly natural to adjust as you engage in the writing process. As we’ve discussed before , writing is a way of developing your thinking, so it’s quite common for your thinking to change – and therefore, for your chapter structure to change – as you write. 

Need a helping hand?

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components – an  introduction , a  body   and a  conclusion . 

Let’s take a closer look at each of these.

1: The Introduction Section

Just like any good introduction, the introduction section of your literature review should introduce the purpose and layout (organisation) of the chapter. In other words, your introduction needs to give the reader a taste of what’s to come, and how you’re going to lay that out. Essentially, you should provide the reader with a high-level roadmap of your chapter to give them a taste of the journey that lies ahead.

Here’s an example of the layout visualised in a literature review introduction:

Your introduction should also outline your topic (including any tricky terminology or jargon) and provide an explanation of the scope of your literature review – in other words, what you  will   and  won’t   be covering (the delimitations ). This helps ringfence your review and achieve a clear focus . The clearer and narrower your focus, the deeper you can dive into the topic (which is typically where the magic lies). 

Depending on the nature of your project, you could also present your stance or point of view at this stage. In other words, after grappling with the literature you’ll have an opinion about what the trends and concerns are in the field as well as what’s lacking. The introduction section can then present these ideas so that it is clear to examiners that you’re aware of how your research connects with existing knowledge .

2: The Body Section

The body of your literature review is the centre of your work. This is where you’ll present, analyse, evaluate and synthesise the existing research. In other words, this is where you’re going to earn (or lose) the most marks. Therefore, it’s important to carefully think about how you will organise your discussion to present it in a clear way. 

The body of your literature review should do just as the description of this chapter suggests. It should “review” the literature – in other words, identify, analyse, and synthesise it. So, when thinking about structuring your literature review, you need to think about which structural approach will provide the best “review” for your specific type of research and objectives (we’ll get to this shortly).

There are (broadly speaking)  three options  for organising your literature review.

Option 1: Chronological (according to date)

Organising the literature chronologically is one of the simplest ways to structure your literature review. You start with what was published first and work your way through the literature until you reach the work published most recently. Pretty straightforward.

The benefit of this option is that it makes it easy to discuss the developments and debates in the field as they emerged over time. Organising your literature chronologically also allows you to highlight how specific articles or pieces of work might have changed the course of the field – in other words, which research has had the most impact . Therefore, this approach is very useful when your research is aimed at understanding how the topic has unfolded over time and is often used by scholars in the field of history. That said, this approach can be utilised by anyone that wants to explore change over time .

For example , if a student of politics is investigating how the understanding of democracy has evolved over time, they could use the chronological approach to provide a narrative that demonstrates how this understanding has changed through the ages.

Here are some questions you can ask yourself to help you structure your literature review chronologically.

• What is the earliest literature published relating to this topic?
• How has the field changed over time? Why?
• What are the most recent discoveries/theories?

In some ways, chronology plays a part whichever way you decide to structure your literature review, because you will always, to a certain extent, be analysing how the literature has developed. However, with the chronological approach, the emphasis is very firmly on how the discussion has evolved over time , as opposed to how all the literature links together (which we’ll discuss next ).

Option 2: Thematic (grouped by theme)

The thematic approach to structuring a literature review means organising your literature by theme or category – for example, by independent variables (i.e. factors that have an impact on a specific outcome).

As you’ve been collecting and synthesising literature , you’ll likely have started seeing some themes or patterns emerging. You can then use these themes or patterns as a structure for your body discussion. The thematic approach is the most common approach and is useful for structuring literature reviews in most fields.

For example, if you were researching which factors contributed towards people trusting an organisation, you might find themes such as consumers’ perceptions of an organisation’s competence, benevolence and integrity. Structuring your literature review thematically would mean structuring your literature review’s body section to discuss each of these themes, one section at a time.

Here are some questions to ask yourself when structuring your literature review by themes:

• Are there any patterns that have come to light in the literature?
• What are the central themes and categories used by the researchers?
• Do I have enough evidence of these themes?

PS – you can see an example of a thematically structured literature review in our literature review sample walkthrough video here.

Option 3: Methodological

The methodological option is a way of structuring your literature review by the research methodologies used . In other words, organising your discussion based on the angle from which each piece of research was approached – for example, qualitative , quantitative or mixed  methodologies.

Structuring your literature review by methodology can be useful if you are drawing research from a variety of disciplines and are critiquing different methodologies. The point of this approach is to question  how  existing research has been conducted, as opposed to  what  the conclusions and/or findings the research were.

For example, a sociologist might centre their research around critiquing specific fieldwork practices. Their literature review will then be a summary of the fieldwork methodologies used by different studies.

Here are some questions you can ask yourself when structuring your literature review according to methodology:

• Which methodologies have been utilised in this field?
• Which methodology is the most popular (and why)?
• What are the strengths and weaknesses of the various methodologies?
• How can the existing methodologies inform my own methodology?

3: The Conclusion Section

Once you’ve completed the body section of your literature review using one of the structural approaches we discussed above, you’ll need to “wrap up” your literature review and pull all the pieces together to set the direction for the rest of your dissertation or thesis.

The conclusion is where you’ll present the key findings of your literature review. In this section, you should emphasise the research that is especially important to your research questions and highlight the gaps that exist in the literature. Based on this, you need to make it clear what you will add to the literature – in other words, justify your own research by showing how it will help fill one or more of the gaps you just identified.

Last but not least, if it’s your intention to develop a conceptual framework for your dissertation or thesis, the conclusion section is a good place to present this.

Example: Thematically Structured Review

In the video below, we unpack a literature review chapter so that you can see an example of a thematically structure review in practice.

Let’s Recap

In this article, we’ve  discussed how to structure your literature review for maximum impact. Here’s a quick recap of what  you need to keep in mind when deciding on your literature review structure:

• Just like other chapters, your literature review needs a clear introduction , body and conclusion .
• The introduction section should provide an overview of what you will discuss in your literature review.
• The body section of your literature review can be organised by chronology , theme or methodology . The right structural approach depends on what you’re trying to achieve with your research.
• The conclusion section should draw together the key findings of your literature review and link them to your research questions.

Great work. This is exactly what I was looking for and helps a lot together with your previous post on literature review. One last thing is missing: a link to a great literature chapter of an journal article (maybe with comments of the different sections in this review chapter). Do you know any great literature review chapters?

I agree with you Marin… A great piece

I agree with Marin. This would be quite helpful if you annotate a nicely structured literature from previously published research articles.

Awesome article for my research.

I thank you immensely for this wonderful guide

It is indeed thought and supportive work for the futurist researcher and students

Very educative and good time to get guide. Thank you

Great work, very insightful. Thank you.

Thanks for this wonderful presentation. My question is that do I put all the variables into a single conceptual framework or each hypothesis will have it own conceptual framework?

Thank you very much, very helpful

This is very educative and precise . Thank you very much for dropping this kind of write up .

Pheeww, so damn helpful, thank you for this informative piece.

I’m doing a research project topic ; stool analysis for parasitic worm (enteric) worm, how do I structure it, thanks.

comprehensive explanation. Help us by pasting the URL of some good “literature review” for better understanding.

great piece. thanks for the awesome explanation. it is really worth sharing. I have a little question, if anyone can help me out, which of the options in the body of literature can be best fit if you are writing an architectural thesis that deals with design?

I am doing a research on nanofluids how can l structure it?

Beautifully clear.nThank you!

Lucid! Thankyou!

Brilliant work, well understood, many thanks

I like how this was so clear with simple language 😊😊 thank you so much 😊 for these information 😊

Insightful. I was struggling to come up with a sensible literature review but this has been really helpful. Thank you!

You have given thought-provoking information about the review of the literature.

Thank you. It has made my own research better and to impart your work to students I teach

I learnt a lot from this teaching. It’s a great piece.

I am doing research on EFL teacher motivation for his/her job. How Can I structure it? Is there any detailed template, additional to this?

You are so cool! I do not think I’ve read through something like this before. So nice to find somebody with some genuine thoughts on this issue. Seriously.. thank you for starting this up. This site is one thing that is required on the internet, someone with a little originality!

I’m asked to do conceptual, theoretical and empirical literature, and i just don’t know how to structure it

Organizing and Writing the Review

Organizing the review, writing the review, online resources.

After selecting the citations for inclusion into the review, it is time to outline and organize the literature review.  There are three basic components of a literature review: Introduction, Body, and Conclusion. Once the details of the outline are complete: it is time to write the literature review chapter of the research paper.   

Introduction to the review.   It should be brief, describing the body of the literature review in terms of format and logical structure. This covers areas such as the research problem, methodology, and the literature that addresses the context of the research study.

Body of the Literature Review . It serves as the logical structure for describing the study’s conceptual or theoretical frameworks. It should cite seminal studies regarding the research problem.  This is where the reviewer can take the liberty of synthesizing what you learned during the course of the literature search. If using subheadings to organize your content in the literature review, then divide by category.

The reviewer may find it useful to format subdivisions of the review. Below are some common subheadings that can divide the review into categories:

• Methodology
• Research findings

Conclusion.   It should also be brief succinctly summarizing what the researcher learned from the review and how it supports the underpinnings of the research study, identifies gaps in the literature and how it justifies the research study.

Writing the Review  You completed all phases in the process. It is time to write the literature review for your research paper. 

Here are a few tips for writing the review

Tip #1:  Know your audience Before writing, identify your audience: who reads the publication where you are submitting your manuscript?

Tip #2:  Avoid jargon Especially if writing for a general audience. Do not use extravagant words.

Tip #3: Keep paragraphs short Pare down excessive wordage when possible. Remember: brevity of content.  Keep review logical structure intact when writing.

Tip #4 : Use subheadings to clarify and lend coherence to review structure Subheadings help organize the review Use subheadings to drill down concepts you cover in the review.

        Tip #5: Focus and preserve continuity Stay on point, keep your focus, and do not stray.

Tip #6: Sustain logical flow Remember, the logical structure of your paper, makes your case in all instances. 

Tip #7: Avoid quotations Use only in rare instances. Always use paraphrasing whenever possible.

Tip #8:   Do not cite references you have not read! If you have not read the article, then DO NOT cite it.

Tip #9:   Use prudence in citing number of studies used Do not cite every source: only sources directly relevant.

Your goal: The reader, upon having read the literature review, should have confidence the author has a thorough understanding of the research topic; the reader has an appreciation of the research problem covered in the study through a grounding of the literature review.

AP 7th Edition Headings

You'll want to use headings to structure your lit review. The APA 7th Additions specifies five levels of headings, in descending levels of emphasis (i. e. level 1 headings are the most important and level 5 headings the least).  The number of headings you use will depend on the length and complexity of your paper, but in any case, make sure to begin with a level 1 heading and proceed sequentially to level 2, then level 3, etc.

The introduction to your paper does not begin with a heading of any kind. Note that there cannot be single level 3, 4, or 5 headings. That is, you must have more than one heading at each of those levels.

Level 1 Headings Are Centered, Title Case and Bold With No Closing Period

Start a new, indented paragraph on the next line after Level 1 headings.

Level 2 Headings Are Flush Left (Not Centered and Not Indented) and Are Title Case and Bold With No Closing Period

Start a new, indented paragraph on the next line after Level 2 headings.

Level 3 Headings Are Flush Left (Not Centered and Not Indented) and Are Title Case, Bold, and Italicized, With No Closing Period

Start a new, indented paragraph on the next line after Level 3 headings.

               Level 4 Headings are Indented Left , Title Case and Bold With a Closing Period. Continue writing the paragraph on the same line after Level 4 headings.

          Level 5 Headings are Indented Left , Title Case , Bold, and Italicized With a Closing Period .  Continue writing the paragraph on the same line after Level 5 headings.

Headings Levels

Level 1 Heading: Centered, Bolded, No Period

          Paragraph will begin on the next line, indented. 

Level 2 Heading: Left-flush, No Indent, Bolded, No Period

           Paragraph will begin on the next line, indented.

Level 3 Heading: Left-Flush, No Indent, Bolded, Italicized, No Period

           Level 4 Heading: Left-Flush, Indented, Bolded, With a Period at the End.  Paragraph will begin on the same line without indentation.

           Level 5 Heading: Left-Flush, Indented, Bolded, Italicized, With a Period at the End.  Paragraph will begin on the same line without indentation.

How to use headings and subheadings

Always begin with Level 1 Headings for a new section. This is the most important heading, and is used to introduce a new section of your paper, like the introduction, body, and conclusion. Levels 2-5 are considered to be subheadings. You must go in order of the Levels when using headings (start with Level 1 and work your way to Level 5).

Most assignments will only use Levels 1-3 for headings. Levels 4-5 are reserved for complex topics or upper-level research. 

There is no rigid formatting for a body paragraph that uses headings and subheadings. Depending on the complexity of your paper, you may use as many levels of headings as you feel is natural in your paper. As long as your headings are properly formatted in the way listed above, then your paper can be structured with as many/few headings as you like. 

To see an example where these headings are used in proper format, please look at this sample paper . 

Special Headings

Section labels are considered to be special headings. They will always begin on a new page of their own, be bolded, and centered. The following sections of a literature review are considered to be section labels:

• Paper Title
• << Previous: Conclusion
• Next: Citations >>

• Comprehensive Guide to Headings and Subheadings in APA 7.0

Section 1: Introduction to Headings and Subheadings in APA 7.0-

In academic writing, the use of headings and subheadings is crucial for organizing and structuring a paper. APA (American Psychological Association) style, specifically in its 7th edition, provides clear guidelines on how to effectively use headings and subheadings to enhance readability and comprehensibility of research papers, essays, and other scholarly works. This section will provide a comprehensive introduction to the importance, purpose, and benefits of using headings and subheadings in APA 7.0 format.

Purpose of Headings and Subheadings

Headings and subheadings serve as visual cues to help readers navigate through the content of a paper. They create a hierarchical structure, indicating the relationships between different sections and subsections, and aid in organizing ideas and presenting information in a logical manner. By using headings and subheadings, writers can effectively divide their work into manageable and coherent sections, making it easier for readers to comprehend and follow the main arguments and supporting details.

Importance of Headings and Subheadings

Clear and well-structured headings and subheadings are essential in academic writing for several reasons. First and foremost, they enhance the overall readability of the paper by breaking down the text into smaller, digestible chunks. This organization allows readers to quickly identify and locate specific information, especially when they are scanning or skimming through the document.

Secondly, headings and subheadings contribute to the coherence and flow of the paper. By providing a clear roadmap, they guide the reader through the main ideas, supporting evidence, and key points presented in each section. This not only improves the overall structure of the paper but also helps maintain the logical progression of thoughts and arguments.

Additionally, headings and subheadings assist both readers and writers in comprehending complex topics. They enable writers to organize their thoughts, ensuring that each section focuses on a specific aspect or theme. This organization facilitates a deeper understanding of the subject matter for both the writer during the drafting process and the reader during the consumption of the paper.

Formatting Guidelines for Headings and Subheadings

APA 7.0 provides specific rules and formatting guidelines for using headings and subheadings. These guidelines include the use of different levels of headings, capitalization rules, and placement within the paper. Understanding and adhering to these guidelines is crucial for maintaining consistency and conformity with APA style.

The APA 7.0 formatting guidelines for headings and subheadings are based on a five-level hierarchy, with each level indicating the level of importance and hierarchy of information. Level 1 headings are the highest level, followed by Level 2, Level 3, and so on. Each level has a specific formatting style, such as font size, boldness, and indentation, to differentiate it from the other levels. Furthermore, APA 7.0 also provides guidance on the appropriate use of sentence case, title case, and capitalization in headings and subheadings. For instance, Level 1 headings are typically written in sentence case and are centered and bolded. Level 2 headings are aligned to the left margin, bolded, and written in title case. To maintain clarity and consistency, APA 7.0 also provides recommendations on the number of headings to use within a paper. It suggests that at least two headings should be used in any given section, as a single heading alone may not adequately represent the content covered.

Section 2: The Purpose and Importance of Headings and Subheadings in APA 7.0

Facilitating information retrieval.

One of the primary purposes of headings and subheadings in APA 7.0 is to facilitate information retrieval for readers. When faced with a lengthy document, readers often engage in scanning or skimming techniques to locate specific information or sections of interest. Well-structured headings and subheadings act as signposts, allowing readers to quickly identify the content they are seeking without having to read the entire text. By providing a clear and organized hierarchy, headings guide readers to the main sections of a paper, while subheadings further break down the content into more specific subsections. This hierarchical structure enables readers to navigate the document with ease, locating relevant information efficiently. Thus, headings and subheadings in APA 7.0 contribute significantly to the overall accessibility and user-friendliness of academic papers.

Enhancing Readability and Comprehensibility

Headings and subheadings play a vital role in enhancing the readability and comprehensibility of academic writing. They help break up large blocks of text into smaller, digestible sections, preventing the overwhelming feeling that dense paragraphs can create. By visually separating different sections and subsections, headings and subheadings allow readers to mentally prepare for the content they are about to encounter. Additionally, headings and subheadings improve the flow and coherence of a paper. They provide a roadmap for readers, helping them understand the organization and structure of the author's arguments and supporting evidence. Well-crafted headings and subheadings enable readers to follow the logical progression of ideas and maintain a clear understanding of the paper's main points. Finally, headings and subheadings aid in the comprehension of complex topics. By breaking down the content into smaller, focused sections, readers can grasp the material more easily. Headings act as cognitive cues, preparing readers for the information presented in each section. This approach not only facilitates understanding but also allows readers to engage with the content at a deeper level, promoting knowledge retention.

Organizing and Structuring Ideas

Headings and subheadings in APA 7.0 serve as valuable tools for organizing and structuring ideas within a paper. They help writers divide their work into meaningful sections, each addressing a specific aspect or theme related to the overall topic. This organization ensures that information is presented in a coherent and logical manner, making it easier for both the writer and the reader to navigate the paper.

By using headings and subheadings, writers can create a clear outline for their work, ensuring that each section has a distinct focus. This outline acts as a framework, guiding the writer in presenting their arguments and supporting evidence in a systematic and organized way. Writers can use headings to delineate major sections or main ideas, while subheadings allow for further subcategorization and exploration of subtopics.

Furthermore, headings and subheadings assist writers in structuring their thoughts during the writing process. By providing a visual representation of the paper's organization, headings help writers maintain a coherent flow of ideas and prevent the inclusion of irrelevant or tangential information. This structured approach not only improves the overall quality of the paper but also enhances the writer's ability to communicate their ideas effectively.

Conveying the Hierarchical Relationship of Information

Another important purpose of headings and subheadings in APA 7.0 is to convey the hierarchical relationship of information. By assigning different levels to headings, the writer can indicate the relative importance and order of ideas within the paper. Higher-level headings represent broader themes or major sections, while lower-level headings address more specific subtopics or subsections. This hierarchical structure helps readers understand the organization and logical flow of the paper at a glance. It allows them to grasp the overall structure and the relationships between different sections without having to read the entire document. Additionally, the use of indentation and formatting styles for each level of heading further reinforces the hierarchical relationship and aids in visual differentiation.

Section 3: Formatting Guidelines for Headings and Subheadings in APA 7.0

Proper formatting of headings and subheadings is crucial in APA 7.0 style to ensure consistency, clarity, and readability in academic writing. This section will delve into the specific formatting guidelines provided by APA 7.0 for headings and subheadings, including the use of different levels, capitalization rules, and placement within the paper.

Levels of Headings

APA 7.0 introduces a five-level hierarchy for headings, each denoting a different level of importance and significance within the paper. These levels provide a structured framework for organizing the content and help readers understand the organization and flow of ideas. Here are the five headings in APA 7.0:

Level 1: Centered, Bold and Title Case

            Text begins here.

Level 2: Left-Aligned, Bold and Title Case

Level 3: Left-Aligned, Bold, Italics, and Title Case

Level 4: Left-Aligned, Bold, Title Case, and Period. Text begins here.

Level 5: Left-Aligned, Bold, Title Case, Italics, and Period . Text begins here.

Section 4: Organizing and Structuring Your Paper

Using headings and subheadings in apa 7.0.

Organizing and structuring your paper effectively is crucial for presenting your ideas in a logical and coherent manner. Headings and subheadings in APA 7.0 play a vital role in achieving this goal by providing a clear framework for organizing your content. This section will delve into strategies and best practices for utilizing headings and subheadings to organize and structure your paper in accordance with APA 7.0 guidelines.

Preparing an Outline

Before you begin writing your paper, it is helpful to create an outline that outlines the main sections and subsections you intend to cover. An outline acts as a roadmap, allowing you to visualize the overall structure and flow of your paper. It serves as a foundation for developing meaningful headings and subheadings that accurately represent the content and facilitate logical organization. Start by identifying the major sections that your paper will include, such as introduction, literature review, methods, results, discussion, and conclusion. These major sections will serve as Level 1 headings in APA 7.0. Next, break down each major section into subsections that address specific subtopics or aspects related to the main theme. These subsections will be represented by Level 2 headings. Depending on the complexity and depth of your paper, you may further divide the subsections into sub-subsections using Level 3, Level 4, and Level 5 headings. Creating a comprehensive outline not only helps you organize your thoughts but also ensures that you cover all the necessary components of your paper. It allows you to see the relationships between different sections and subsections, enabling you to present your arguments and evidence in a logical and coherent sequence.

Maintaining Consistency and Parallelism

Consistency is key when it comes to organizing and structuring your paper using headings and subheadings. It is important to establish a consistent framework that is followed throughout the entire document. Consistency ensures that readers can easily understand the hierarchy and relationships between different sections and subsections. When creating headings and subheadings, aim for parallelism in terms of grammatical structure and formatting. Parallelism means that headings at the same level should have a similar grammatical structure and formatting style. For instance, if you choose to use noun phrases for Level 2 headings, maintain this pattern consistently across all Level 2 headings in your paper. This helps readers navigate through the content smoothly and maintain a sense of coherence. Furthermore, parallelism extends to the use of punctuation and capitalization within headings and subheadings. Maintain consistent capitalization rules, such as sentence case for Level 1 headings and title case for Level 2 headings. This uniformity enhances the visual hierarchy and clarity of your paper.

Balancing Depth and Granularity

Effective organization and structuring involve finding the right balance between depth and granularity in your headings and subheadings. Level 1 headings represent major sections and should encapsulate broad themes or concepts, providing an overview of what will be discussed within each section. Level 2 headings, as subsections, delve into more specific topics or aspects related to the main theme of the major section.

Reviewing and Revising the Organization

Organizing and structuring your paper using headings and subheadings is not a one-time task. It is an iterative process that requires regular review and revision to ensure optimal clarity and coherence. Once you have completed the initial draft of your paper, review the organization of your headings and subheadings. Ask yourself if the structure effectively reflects the flow of your ideas and supports your main argument. Consider whether the headings accurately represent the content of each section and subsection. During the review process, pay attention to transitions between sections and subsections. Ensure that the headings and subheadings create a smooth transition from one topic to another, guiding readers through the logical progression of your paper. If you notice any gaps or inconsistencies, revise and refine the organization accordingly. Additionally, seek feedback from peers, mentors, or instructors. Their fresh perspective can provide valuable insights into the clarity and effectiveness of your headings and subheadings. Incorporate their feedback and make necessary adjustments to improve the overall organization and structure of your paper.

Section 5: Common Mistakes to Avoid in Using Headings and Subheadings in APA 7.0

While using headings and subheadings in APA 7.0 can greatly improve the organization and readability of your paper, it's important to be aware of common mistakes that can compromise the effectiveness of your headings. By understanding and avoiding these mistakes, you can ensure that your headings enhance the clarity and coherence of your academic writing. This section will explore some common mistakes to avoid when using headings and subheadings in APA 7.0.

Inconsistent Formatting

One of the most common mistakes is inconsistent formatting of headings and subheadings. In APA 7.0, it is crucial to maintain consistency in capitalization, alignment, and formatting styles across headings at the same level. Inconsistencies can confuse readers and disrupt the visual hierarchy of your paper. Ensure that all Level 1 headings have the same formatting, all Level 2 headings have the same formatting, and so on. Consistency in formatting contributes to the overall professionalism and readability of your work.

Poor Alignment and Spacing

Another mistake to avoid is incorrect alignment and spacing of headings and subheadings. In APA 7.0, Level 1 headings are centered and typically start on a new page or a new line with an extra line space before and after the heading. Level 2 headings and lower-level headings, however, are left-aligned and generally require an extra line space before the heading but not after. Failure to align and space headings correctly can create confusion and disrupt the logical flow of your paper. Review APA 7.0 guidelines carefully to ensure proper alignment and spacing of your headings.

Lack of Parallelism

Parallelism, or consistent grammatical structure, is crucial when using headings and subheadings. Headings at the same level should follow a similar structure to maintain coherence and readability. For example, if you use noun phrases for Level 2 headings, ensure that all Level 2 headings follow this pattern. Lack of parallelism can make your headings appear disjointed and may confuse readers. Consistently apply parallel structure within each level of headings to create a smooth and organized flow of information.

Overcomplicating the Heading Structure

While it is important to provide a clear and hierarchical structure to your paper, overcomplicating the heading structure can lead to confusion and excessive fragmentation. Strive to find a balance between providing enough detail to cover your content effectively and avoiding an excessive number of headings and subheadings. Each heading should represent a meaningful subdivision and contribute to the overall organization and coherence of your paper. Aim for a clear and concise heading structure that guides readers without overwhelming them with excessive levels or overly specific subdivisions.

Lack of Descriptiveness

Headings and subheadings should be descriptive and informative to accurately represent the content covered within each section. Avoid using generic or ambiguous headings that do not provide a clear indication of what readers can expect to find. Vague headings can leave readers uncertain about the content or make it challenging to locate specific information within your paper. Ensure that your headings succinctly capture the main ideas or themes of each section, guiding readers through your content effectively.

Ignoring the Reader's Perspective

When creating headings and subheadings, it's important to consider the perspective of your readers. Put yourself in their shoes and think about how your headings will facilitate their understanding and navigation through your paper. Consider whether your headings effectively communicate the main points, guide readers through the logical flow of your arguments, and enable them to locate specific information easily. Ignoring the reader's perspective can result in headings that are unclear, unhelpful, or inconsistent, hindering the overall readability and comprehension of your work.

Neglecting to Revise and Edit Headings

Headings should not be an afterthought or treated as static elements in your paper. Neglecting to revise and edit your headings can lead to inaccuracies, lack of clarity, or poor alignment with the final content of your paper. As you progress through the writing process, continuously review and refine your headings to ensure they accurately represent the content and flow of your arguments. Make necessary adjustments, reword headings for better clarity, and ensure that they align with the finalized structure and organization of your paper.

Writing a literature review for a research paper is an important stage in the academic research process. It entails doing a critical review of existing literature to provide a comprehensive overview of current knowledge on a certain issue. In this article, we will walk you through the important processes for writing an excellent literature review. We’ll discuss how to discover relevant literature, combine findings, and arrange your review to provide clear insights. Whether you’re a seasoned researcher or a first-time writer, this guide will give you essential advice and tactics for improving the quality and impact of your literature reviews.

What Is a Literature Review?

A literature review is a survey of key scholarly sources to do with a particular topic. It lists a number of important and relevant pieces of writing and, in doing so, gives the reader a summary of the topic’s current knowledge and debates. When writing a literature review, a student should do more than just summarise each individual source. They should analyze them closely and compare them with one another.

A key part of academic writing involves understanding what has been said and debated about the chosen topic. Once a student has done their research, they’re in a better place to write their research paper and put their point across. A good literature review should let the reader know what the salient points from the student’s research are.

What Is the Purpose of a Literature Review?

The purpose of a literature review is to show the reader what research has been carried out on the chosen topic in the past. When writing one, you’re aiming to bring the reader up to speed with other people’s research before sharing your own findings. You should summarise where the topic’s at right now before building on it with your research.

Another important purpose is to give more weight to a student’s key arguments. By listing and comparing some of the key sources, a student can give context to the main points in their research paper; they can even fill any gaps in certain areas that others haven’t yet managed to fill.

If you want to know how to write a literature review in a research paper, carry on reading. We’ll run you through the process of putting one together, and we’ll talk about some of the different approaches you can take in writing one.

Steps in the Literature Review Process

A literature review can make a Ph.D. dissertation, or any other kind of  research paper more convincing. For a review to be effective, it should be detailed and have substance but without overdoing it; in other words, it should be concise.

If you’re not sure how to write a literature review for a research paper, we’ll show you how in this section. Here are the main steps to take:

• Decide on your topic Your topic is the base on which you build your research. It also determines what research you carry out.
• Search for sources to include The sources you look at for your research paper should be authoritative and relevant. They should be scholarly in nature, though not all of them will be.
• Determine which ones are the most useful Look through your sources and think about how much each one adds to both the topic you’re exploring and the research you’re carrying out. Including all sources isn’t practical, so only choose the most appropriate and fitting ones.
• Identify where the research is currently at By reading other people’s research, you can get an idea of what the current thoughts and debates relating to your chosen topic area.
• Come up with a structure Literature reviews have quite simple structures. More information on these is given below. Think about how you want to present yours and how you’re going to arrange your findings.
• Write your literature review A well-written literature review gives the reader all the necessary information about each of the sources. It clearly explains how the sources are connected and what they contribute to the chosen topic.

It’s a good idea to come up with headings and subheadings and go from there. These are both important, and we’ll talk about them in more detail later on. During the planning process, they can help you come up with a definitive structure for your literature review and consolidate your thoughts.

You may want to pay someone to write a literature review for you. Many people who are struggling with literature reviews do this. They don’t hand in the work that someone else has done for them. Instead, they read through the other person’s work to get ideas and inspiration. Doing this can help people write their own literature review much more effectively.

How to Structure a Literature Review

For this section, we’ll look at how to write a literature review. We’ll focus on the different approaches you can take according to the type of research you’re doing and how you wish to present it.

Chronological

Listing your sources in chronological order is perhaps the simplest approach to take. However, make sure you don’t just list the sources and summarise them. You should still try to establish some sort of connection between them. Highlight movements, patterns, and new ideas. Show the reader how scholarship on the topic has changed over time. You could even organize your sources into broad historical periods and have these as subheadings in the literature review, for example.

When writing a thematic literature review , you should organize your sources by theme. You should consider this approach if you’ve found multiple themes during your research. Create literature review subheadings for each theme that stands out to you. If you go for a thematic style, think about what your RRL subtopics are and what themes you would use to organize them.

Methodological

A methodological literature review is one whose sources involve the use of different research methods . You could have one source that’s numerical and involves graphs and statistics, for example, and another that’s entirely made up of written text. The subheadings in a literature review that’s methodological could focus on different types of research, focusing not so much on what has been researched but how it’s been researched. As a literature review subheadings example, you could therefore have one subheading for literary sources, another for numerical/graph-based data, and so on.

Theoretical

With a theoretical approach, the focus is on the body of theories relating to the topic that’s being discussed. The aim is to determine what theories there currently are, how they relate to one another, and how much they’ve been looked into.

These are just some of the different ways you can go about writing a literature review. The approach you take will depend on the nature of your review and the topic you’re looking at.

Writing a literature review can be an intimidating task to tackle, especially if you are not familiar with the literature in the field. Fortunately, there is a  paper writing service online that can help you create an outstanding literature review in no time. Our service is helpful for students, researchers, and others who need to compile a comprehensive and informative literature review.

Literature Review Outline

Writing a good outline for a literature review is important for your research paper. It helps you organize your thoughts and ideas and gives you a clear direction for the writing process.

An outline is not a formal document but rather an informal guide to assist you in organizing the information you want to include in your paper. The outline should be written in paragraph form, with each paragraph representing one major idea that will be expanded upon in subsequent paragraphs of the paper.

The main purpose of writing an outline is so that you can organize all of your sources in a way that will help you write a clear, concise essay. You just want to throw together quotes and facts without any order or reason. This will make it hard for the reader to follow along with what you are saying and make it appear that you have no idea what you’re talking about. This can result in a low grade for your paper and make it difficult for them to understand what is happening within the text.

• Introduction The introduction should include a brief summary of the literature that is being reviewed, including the general topic and your specific focus. You should also provide some background information on the topic to help the reader understand why it is important. You should not include any citations in this section, because you will do that later in the paper.
• Body The body is where you provide an overview of all the sources or literature, you have used for your paper. You should include an introduction to each source and a brief summary of what was found in each source. In addition to providing summaries, you should also describe how each source relates to your research question or hypothesis and then relate them back to each other if they are similar enough to be compared. Finally, you should explain how each source relates to one another in addition to explaining how they relate to your research question or hypothesis.
• Conclusion The conclusion should summarize your arguments throughout the paper and then tie all of these things together into one coherent argument that proves or disproves your hypothesis or research question in relation to other sources discussed throughout this paper (and/or).

Writing a literature review is an integral part of a successful research article or dissertation, as it helps to synthesize and connect the existing body of knowledge. To write your lit review relevantly, it is important to ensure that you include new information when constructing your review and connect existing ideas and themes. A useful literature review outline can provide a structure for expressing your views, allowing you to connect and organize your ideas consistently and effectively.

Literature Review: Writing Tips

When writing a literature review, it’s important to include all of the information your assignment requires. Sometimes, instructors will give you specific guidelines for how long your literature review should be and how many sources it needs to include. If they don’t, however, you’ll need to decide what works best for your situation.

A literature review outline will be the foundation of your paper. It will tell you what information is important and how to write it cohesively and logically. When writing, it’s important to only include facts backed up by evidence. This means that if you are writing about any research topic, there must be at least one piece of published work that backs up each claim or opinion you present.

If there isn’t a source supporting your writing, don’t put it in because it makes your paper seem like speculation or opinion rather than fact-based knowledge about the issue at hand. Another tip for writers is to write clearly and concisely so that readers can understand what they are reading quickly without having any difficulty following along from one point to another throughout the entire essay (or book).

Readers may get bored very quickly if they feel like they have to struggle through something too much before getting into where things go next. Therefore, proper grammar usage should also be kept while doing this type as well, so there are no mistakes left behind after editing later down the line during the publishing stage itself.

The following are the most important tips for writing a literature review:

• Make sure that each paragraph covers a single subject or idea.
• Start with a thesis statement, which should sum up the paper’s main idea in one sentence.
• Write each paragraph in a way that flows from one point to another logically and coherently.
• Include quotes and paraphrases from sources you have read in order to support your arguments and conclusions.
• Make sure that you use credible sources as evidence for your claims and arguments in your paper.

As well as learning how to write a literature review for a research paper, you’ll learn to be more productive and use your time more wisely. Writing services help you put together literature reviews more efficiently. They give you the opportunity to work with an experienced writer who can offer tips in writing RRL, help you with literature review formatting, and more. For example, you can even get things like literature review headings and subheadings so you can see how best to write your headings.

Remember that while the literature review isn’t the main part of a research assignment, it’s still significant. It’s important that you write it as best you can so that your research has more backing and will be taken more seriously.

How do I style headings and subheadings in a research paper?

Headings and subheadings can help organize and structure your writing. In general, longer and more complex works warrant more of them than shorter ones. Avoid overusing headings in short projects; they should never be used to compensate for poor structure or to explain an underdeveloped idea.

When headings are called for in your writing project, observe the basic guidelines below.

The paper or chapter title is the first level of heading, and it must be the most prominent.

Headings should be styled in descending order of prominence. After the first level, the other headings are subheadings—that is, they are subordinate. Font styling and size are used to signal prominence. In general, a boldface, larger font indicates prominence; a smaller font, italics, and lack of bold can be used to signal subordination. For readability, don’t go overboard: avoid using all capital letters for headings (in some cases, small capitals may be acceptable):

Heading Level 1

Heading Level 2

Heading Level 3

Note that word-processing software often has built-in heading styles.

Consistency

Consistency in the styling of headings and subheadings is key to signaling to readers the structure of a research project. That is, each level 1 heading should appear in the same style and size, as should each level 2 heading, and so on. Generally avoid numbers and letters to designate heads unless you are working in a discipline where doing so is conventional. Note that a heading labeled “1” requires a subsequent heading labeled “2,” and a heading labeled “a” requires a subsequent heading labeled “b.” 

In a project that is not professionally designed and published, headings should be flush with the left margin, to avoid confusion with block quotations. (The exception is the paper or chapter title, which is centered in MLA style.)

For readability, it is helpful to include a line space above and below a heading, as shown in this post.

No internal heading level should have only one instance. For example, if you have one level 1 heading, you need to have a second level 1 heading. (The exceptions are the paper or chapter title and the headings for notes and the list of works cited.) You should also generally have text under each heading.

Capitalization

Capitalize headings like the titles of works, as explained in section 1.5 of the MLA Handbook .

The shorter, the better.

Formatting Research Paper Headings and Subheadings

Different style guides have different rules regarding the formatting of headings and subheadings in a paper, but what information you should actually put into your subheadings is a different question and often up to personal taste. Here we quickly summarize general guidelines, different approaches, and what not to do when choosing headings for a research paper.

Does it matter how I name my sections and subsections?

The main sections of a research paper have general headers and are often journal-specific, but some (e.g., the methods and discussion section) can really benefit from subsections with clear and informative headers. The things to keep in mind are thus the general style your paper is supposed to follow (e.g., APA, MLA), the specific guidelines the journal you want to submit to lists in their author instructions , and your personal style (e.g., how much information you want the reader to get from just reading your subsection headers).

Style Guides: Research Paper Heading and Subheading Format

Headers identify the content within the different sections of your paper and should be as descriptive and concise as possible. That is why the main sections of research articles always have the same or very similar headers ( Introduction, Methods, Results, Discussion ), with no or only small differences between journals. However, you also need to divide the content of some of these sections (e.g., the method section) into smaller subsections (e.g., Participants, Experimental Design, and Statistical Analysis ), and make sure you follow specific journal formatting styles when doing so. 

If the journal you submit to follows APA style , for example, you are allowed to use up to five levels of headings, depending on the length of your paper, the complexity of your work, and your personal preference. To clearly indicate how each subsection fits into the rest of the text, every header level has a different format – but note that headers are usually not numbered because the different formatting already reflects the text hierarchy.

APA style headings example structure

Level 1 Centered, Bold, Title Case

Text begins as a new paragraph.

Level 2 Left-aligned, Bold, Title Case

Level 3 Left-aligned, Bold Italic, Title Case

Level 4     Indented, Bold, Title Case, Period . Text begins on the same                    

                                 line and continues as a regular paragraph.

Level 5     Indented, Bold Italic, Title Case, Period. Text begins on the                           

                                 same line and continues as a regular paragraph.

If you only need one section header (e.g. Methods ) and one level of subsection headers (e.g., Participants, Experimental Design, and Statistical Analysis ), use Level 1 and Level 2 headers. If you need three levels of headings, use Levels 1, 2, and 3 (and so on). Do not skip levels or combine them in a different way. 

If you write a paper in Chicago style or MLA style , then you don’t need to follow such exact rules for headings and subheadings. Your structure just has to be consistent with the general formatting guidelines of both styles (12-pts Times New Roman font, double-spaced text, 0.5-inch indentation for every new paragraph) and consistent throughout your paper. Make sure the different formatting levels indicate a hierarchy (e.g., boldface for level 1 and italics for level 2, or a larger font size for level 1 and smaller font size for level 2). The main specifics regarding Chicago and MLA headings and subheadings are that they should be written in title case (major words capitalized, most minor words lowercase) and not end in a period. Both styles allow you, however, to number your sections and subsections, for example with an Arabic number and a period, followed by a space and then the section name. 

MLA paper headings example structure

1. Introduction

2. Material and Methods

2.1 Subject Recruitment

2.2 Experimental Procedure

2.3 Statistical Analysis

3.1 Experiment 1

3.2 Experiment 2

4. Discussion

5. Conclusion

What research paper headings do you need?

Your paper obviously needs to contain the main sections ( Introduction, Methods, Results, Discussion, and maybe Conclusion ) and you need to make sure that you name them according to the target journal style (have a look at the author guidelines if you are unsure what the journal style is). The differences between journals are subtle, but some want you to combine the results and discussion sections, for example, while others don’t want you to have a separate conclusion section. You also need to check whether the target journal has specific rules on subsections (or no subsections) within these main sections. The introduction section should usually not be subdivided (but some journals do not mind), while the method section, for example, always needs to have clear subsections.

How to Name Your Sections and Subsections

The method section subheadings should be short and descriptive, but how you subdivide this section depends on the structure you choose to present your work – which can be chronological (e.g., Experiment 1, Experiment 2 ) or follow your main topics (e.g., Visual Experiment, Behavioral Experiment, Questionnaire ). Have a look at this article on how to write the methods for a research paper if you need input on what the best structure for your work is. The method subheadings should only be keywords that tell the reader what information is following, not summaries or conclusions. That means that “ Subject Recruitment ” is a good methods section subheading, but “ Subjects Were Screened Using Questionnaires ” is not.  

The subheadings for the result section should then follow the general structure of your method section, but here you can choose what information you want to put in every subheading. Some authors keep it simple and just subdivide their result section into experiments or measures like the method section, but others use the headings to summarize their findings so that the reader is prepared for the details that follow. You could, for example, simply name your subsections “ Anxiety Levels ” and “ Social Behavior ,” if those are the measures you studied and explained in the method section. 

Or, you could provide the reader with a glimpse into the results of the analyses you are going to describe, and instead name these subsections “ Anxiety-Like Behaviors in Mutant Mice ” and “ Normal Social Behaviors in Mutant Mice .” While keeping headings short and simple is always a good idea, such mini-summaries can make your result section much clearer and easier to follow. Just make sure that the target journal you want to submit to does not have a rule against that. 

Common Heading and Subheading Mistakes 

Subheadings are not sentences.

If your heading reads like a full sentence, then you can most probably omit the verb or generally rephrase to shorten it. That also means a heading should not contain punctuation except maybe colons or question marks – definitely don’t put a period at the end, except when you have reached heading level 4 in the APA formatting style (see above) and the rules say so.  

Be consistent

Always check your numbering, for example for spaces and periods before and after numbers (e.g., 3.2. vs 3.2 ), because readability depends on such features. But also make sure that your headings are consistent in structure and content: Switching between short keyword headings (e.g., “ Experiment 2 ”) and summary headings (e.g., “ Mice Do not Recognize People ”) is confusing and never a good idea. Ideally, subheadings within a section all have a similar structure. If your first subsection is called “ Mice Do not Recognize People ,” then “ People Do not Recognize Mice” is a better subheader for the next subsection than “Do People Recognize Mice? ”, because consistency is more important in a research paper than creativity. 

Don’t overdo it

Not every paragraph or every argument needs a subheading. Only use subheadings within a bigger section if you have more than one point to make per heading level, and if subdividing the section really makes the structure clearer overall.

What are Subheadings?

How subheadings can help you.

• Pulling it all together

MEDLINE and CINAHL have yet another tool for narrowing your search results: Subheadings. These are not to be confused with Sub JECT Headings, but they are closely associated with them.

Once you select a particular Sub JECT Heading to use in your search strategy, the database will offer a list of subheadings that are specific to that term, which will help to focus on a particular aspect of the topic.

For example, suppose you are researching the West Nile Virus. Here is the list of subheadings offered by Ovid MEDLINE for that term:

What particular aspect of this virus are you interested in? If you are mostly interested in the genetics of this virus, then you might select the Genetics subheading. If you are interested in the immunology of the virus, then choose that subheading. If you are interested in many aspects, then you're better off accepting the default of All Subheadings.

The use of subheadings will almost always result in a smaller set of results, sometimes very much smaller. That can be helpful in some situations because the results will be very narrowly focused on that particular aspect of the topic.

However, just as with the Focus feature, when you use subheadings, you run the risk of missing relevant articles. That's because whether or not a particular subheading is assigned to the article is a highly subjective decision, especially since some subheadings can be quite similar, e.g., Genetics vs Immunology vs Physiology.

Bottom line:

1. Subheadings may be useful when you are in the initial stages of a search on a very broad topic, because they will bring up articles that are known to be "on topic". After you have read those articles and gained familiarity with the topic, you can then revert to searching on "All Subheadings" to conduct a more thorough search. 

2. Subheadings may be useful when the topic you are searching is very broad, e.g., diabetes, stroke, heart disease, and you need some tool to drop the numbers and help narrow the results.

3. Subheadings may be helpful in situations when you just need something good, quickly. This can be a huge time-saver.

Bottom Bottom Line: Use subheadings with caution, and remember that they may drastically reduce the number of results.
