Literature Review in Research Papers: Purpose, Structure, and Example

Professors keep telling you that you must master the literature review in research writing, but they fail to share the skills and tools to complete this challenging task. So, most students assume summarizing a few sources is enough to pass for a literature review in research paper, only to get poor grades and condescending feedback. What are you doing wrong? What is literature review in research if not a summary? We’re here to give you answers, explain typical layouts, and provide an example to follow.

What Is a Literature Review in a Research Paper?

A literature review in research paper is an overview of the current knowledge and consensus in your chosen field of study, based on credible sources. It is a critical component that provides context for your readers, including your professor.

Purpose and Importance of a Literature Review in Research Papers

The main purpose of literature review in research writing is to position your study among recognized publications in the field. While it seems like a tall order, that’s exactly what you achieve when fulfilling other tasks, such as

• Provide background information and context for your audience
• Highlight opposing views and misalignment among topic experts
• Showcase your familiarity with the research field and main publications
• Evaluate the current state of the research field

Even if you’re only thinking about getting a passing grade, remember that professors will use your literature review in research assignments to gauge your ability for independent study, your common sense in choosing reliable sources, and your analytical and critical thinking skills.

Where Does the Literature Review Appear in a Research Paper?

As we’ve established, the role of literature review in research is to provide context and identify knowledge gaps. And its placement in the structure of a research paper derives directly from this purpose. The literature review is the first section of a research paper, following directly after the introduction. Methodology usually follows the literature review in research papers before you can present your results and their discussion, along with recommendations and conclusions.

Literature Review Structure

Whether you’re writing a standalone piece or drafting a literature review in research context, it should still follow the basic three-piece structure:

1. The introduction is where you present your general research field and explain its relevance. In short, the literature review introduction should answer the question, “So what?” or “Why should anyone care?”
2. Body paragraphs are where you analyze your references, synthesize new information, and identify knowledge gaps and limitations in existing data. They are usually the hardest to structure, because you have to order information from a dozen different sources to make sense.
3. The conclusion is the final section of a literature review in a research paper, where you narrow down general data into a specific research question to highlight the goals of your study. If possible, the conclusion should also bridge the gap between the literature review and the methodology section.

To help you order the bulk of your literature review in research paper writing, pick one of three common layouts in the table below:

Literature review structure	Brief description	Examples
Chronological	Present historical trends, changes over time, and compare and contrast data from different periods	Examine the influence of TV shows on teenagers from the 1950s to the present day, decade by decade
Thematic	Focus on different aspects of the research question, explore multiple angles, and consider different approaches	Present the impact different music genres had on pop culture, social interactions, and the economy
Methodological	Explore data derived from different research approaches: theoretical and empirical, qualitative and quantitative	Compare data from student surveys and in-depth one-on-one interviews regarding their perception of campus gun violence

Thematic literature review in research is the most common, so stick with it if you don’t know which approach to pick.

Common Mistakes in Literature Reviews

Reading won’t teach you to write excellent research papers, unless you put this newfound knowledge to the test. But first, let us share a few mistakes to avoid. Here’s what can ruin a literature review in research paper writing:

• Poor choice of references. It’s not enough to find a source that aligns with your topic. It should be credible and objective, without introducing any biases. Using weak sources will undermine your whole paper.
• Summary without analysis. Literature review in research is not an annotated bibliography. It’s not enough to describe what the sources state; you need to explain why this information matters to your study and what it means.
• Proving a point. A literature review in a research paper is not an argumentative essay, either. Your goal is to present data objectively, without convincing the audience to take your side.
• Messy ideas without structure. Listing the main takeaways from references in a random order will make your lit review unreadable. Instead, use one of the approaches we shared to create a strong layout.

Short Example of Literature Review in a Research Paper

A complete literature review in research paper would be too much for such a short blog post. So, instead, we’ll share a passage or two highlighting all the writing tricks we’ve discussed:

According to Smith (2020), over 70% of adolescents demonstrate signs of smartphone addiction, characterized by over 4 hours of screen time daily. At the same time, the survey relied solely on self-report data, rather than tracking applications, as reported by Meyers (2022). Both studies focus on smartphone use duration, whereas data on application use and its psychological and cognitive impacts are lacking. Most studies, such as Lee (2024), focused on application tracking rely on small sample sizes, which may not be reproducible across different cohorts.
