When you’re writing a research paper, having a clear summary of what’s already been studied is super important. It helps you show that you know what other researchers have found and gets your own study off on the right foot.

In this guide, we’re going to walk you through the steps to make this process as easy as possible. No matter if you’re a seasoned researcher or just starting out, these tips will help you write a great literature review without all the confusion.

What is a Literature Review?

According to experts like Cooper (1998) and Ridley (2008), a literature review is a thorough look at what other scholars have written about a specific topic. It involves analyzing, evaluating, and summarizing what’s already known to find out the main ideas and spots where more research is needed.

This careful examination of written work helps us understand how ideas and theories have changed over time in a certain field.

You often find literature reviews in academic papers. They give background and a framework for a study, helping researchers see where their work fits in with what’s already been studied.

Usually, a literature review shows up early in a research paper, after the introduction and before the methods section. Sometimes, it’s part of the introduction itself.

Purpose of a Literature Review in Research Paper 

The role of a literature review in a research paper is crucial. Let’s break it down:

• Providing Background: It gives the background of the research topic, helping to set the stage and explain why it’s important.

• Spotting the Missing Pieces: It helps to find where there are gaps or questions in the existing research.
• Building a Framework: It helps in creating the structure for the study, providing a solid starting point.
• Understanding Previous Work: It helps to understand the methods used in past research and allows us to look closely at key studies and how they were done.
• Pulling Information Together: It helps to combine different sources to create a clear picture of the topic.
• Avoiding Repeating Things: By acknowledging what has already been done, it helps to make sure we’re not saying the same things over again.
• Making Arguments Stronger: By using information from established sources, it makes our arguments stronger and more convincing.
• Putting Things in Context: It helps to place our research in the wider context of what’s already been studied, adding to what we know.

What Are The Parts of a Literature Review?

When you’re writing a literature review, you’ll usually break it down into a few main parts:

• Introduction: This is where you give some background info, explain what you’re looking at, and say what you want to achieve.
• Main Section: Here, you organize the research you’ve found into themes, time periods, or methods, and give a summary of what’s been said, your thoughts on it, and whether it’s good or not.
• Discussion/Analysis: This is where you bring together what you’ve found, talk about what it all means, and point out any gaps or areas where more research is needed.
• Conclusion: Finally, you wrap things up by summarizing what you’ve found, highlighting any important points, and suggesting what could be looked at next.

Next, we’ll take a closer look at how to actually do a literature review step by step.

Step 1: Conduct a Literature Search   

Before you start writing your research paper, you’ll need to gather information that’s related to your topic. This process is called a literature review.

To give you a clearer idea of how to begin writing a literature review, let’s look at an example:

Let’s break down the problem we’re researching and list the main words we need to focus on:

Once you’ve picked out the main words, you can hop on various platforms to dig into your topic. Put those words into your searches to find books and articles that relate to what you’re writing about.

Here are some websites where you can find articles and journals:

• JSTOR
• ScienceDirect
• IEEE Xplore
• SpringerLink
• Google Scholar
• PubMed
• Scopus
• PsycINFO
• ERIC (Education Resources Information Center)

Step 2: Assess and Choose Sources 

Assess the trustworthiness, importance, and reliability of the sources you’ve found. Opt for articles, books, and websites that are well-respected and reliable.

When selecting sources, focus on those that directly relate to your research question. Ask yourself:

• What’s the main question the author is addressing?
• How does this source explain the important ideas for your research?
• What methods or theories does it use?
• Does it offer new insights or just repeat what’s already known?
• What are the main findings?
• How does this source fit with what’s already been written?
• Is it adding something new or challenging what’s already known?
• What are the strong and weak points of the research or information presented?

Tip: Take notes as you read for your literature review. Consider creating an annotated bibliography with full details and brief summaries for each source. It’ll help you remember what you’ve read and save time later on.

Step 3: Find Themes, Debates, and Research Gaps

Take a good look at the articles you’ve been reading. Pay attention to what they talk about a lot, where they might disagree, and what topics they don’t cover. It’s important to understand how these articles connect. Here’s what you should keep an eye out for:

• Spotting Changes Over Time: See if there are any noticeable shifts in how people research or what they find.
• Common Ideas: Look for recurring themes that pop up often in the articles.
• Different Opinions: Notice where the articles don’t agree with each other.
• Important Studies: Find out which studies have made a big impact on the field.
• Missing Pieces: Figure out what’s not included in the articles and what they might have overlooked.

This step helps you get your literature review organized and shows how your research adds to what’s already known.

Step 4: Structure Your Literature Review

Make sure your literature review is well-organized. Depending on the length of your review, pick a way to structure it that fits your research paper. One way is to organize it by method, where you discuss events in the order they occurred.

Now, let’s dive into how to arrange your literature review in a research paper:

Chronological Method

This method sorts information by the order in which events, studies, or ideas were first introduced.Start with the oldest relevant research and move forward in time. This helps readers see how the topic has changed over the years and understand its history.

Thematic Method

The thematic approach to organizing your writing is all about grouping similar ideas together. Instead of sorting through piles of information, you focus on finding common themes or ideas that pop up often. Then, you can arrange your writing based on these themes. This way, your work becomes more organized and easier for others to understand.

Methodological Method

This approach sorts out the literature based on how studies were conducted.By grouping studies with similar ways of conducting research, readers can easily see the different methods used in the literature. This is helpful for anyone curious about how research is done.

Theoretical Method 

In this method, we arrange the literature based on relevant ideas or concepts. We group together sources that share similar ideas, showing how different studies support or question these concepts. This method helps readers understand the background of the research topic in simpler terms.

Publication Method 

This method involves arranging the literature based on when it was published. You present the information in a timeline, starting with the oldest publications and moving towards the newest. This way, you show how research has progressed over time.

Trend Method

When organizing content, you can look for current trends or patterns in the literature. Find and group studies that contribute to or reflect ongoing trends in the research area. This method offers a contemporary perspective on the subject, highlighting the latest advancements in the field.

Step 5: Write the Literature Review

Once you’ve planned out the layout of your literature review, it’s time to dive into writing it. Think of it like putting together an essay – you’ll need an introduction, a main section, and a conclusion.

Start with the Introduction

When you kick off your literature review, be crystal clear about what you’re focusing on and why. If you’re writing a dissertation or thesis, remind folks about the main problem or question you’re digging into.

Give a quick summary of what experts have said, pointing out why this topic matters now or where there are gaps in what’s been studied.

Quick Tip: If it fits, talk about recent studies or things earlier research might have missed.

Create a Detailed Body

When you’re putting together your literature review, adjust how it’s organized based on how much there is to cover. Break it down into smaller sections with titles to focus on the main topics, time periods, or methods.

Here’s what to keep in mind as you write:

• Summarize and Connect: Give a quick overview of the important ideas from each source and link them together to tell a complete story.
• Evaluate Fairly: Talk about what’s good and what’s not so good about the sources to show you really understand them. Pay attention to how studies were carried out or if there are any issues.
• Share Your Thoughts: Go beyond just repeating facts by adding your own ideas and talking about the bigger picture.
• Write Clearly: Put your ideas into well-structured paragraphs with clear main points and smooth transitions. Connect your ideas and compare and contrast different sources.

Tip: Think about using a storytelling approach to lead the reader through the main themes or methods you’ve chosen. Use words like “also,” “however,” or “similarly” to help your writing flow smoothly.

Write a Strong Conclusion

Summarize the main discoveries from the articles and stress why they’re important. Explain how your research fills gaps and brings in new insights. Discuss how you used existing ideas and methods to shape your own study.

Tip: Clearly show how your work adds to or questions what we already know in this area.

Different Types of Literature Reviews 

Here’s a simple chart listing the usual kinds of literature reviews:

Type of Literature Review	Description
Narrative Literature Review	Comprehensive overview without a specific methodology
