This article is not written for guidance, but it has examples to help you write a great dissertation without facing any problems.

What Is a Literature Review?

One should know what a literature review is before starting to write it. Literature review is a complete summary of academic work, for example, articles in journals, books, conference papers, and reports that are linked to a particular topic. It helps you know what else people have written about this topic earlier, what is missing or incomplete in the research, and what your own research can contribute to the existing study. In simple words literature review answers all the questions that I mentioned in the previous sentence. It is not only the discussion of others’ work but a serious literature review in which you analyse the strengths, flaws, and importance of others’ studies.

Purpose of a Literature Review

Here are some points that tell the objective of the literature review and how it can help you give your research a strong foundation. 

1. It helps to focus on topics that were left to be discussed in detail previously.
2. It helps and shows that you understand the topic of your research.
3. It gives you the most relevant information according to your research idea.
4. It will help you write a new piece of research, making sure nothing is repeated from the previous studies.
5. It helps you to write clear research goals or slightly changed research goals based on other researchers’ goals.  

Steps on How to Write a Literature Review

The following are the steps that will guide you in writing a literature review.

Step 1: Define Your Research Focus

From the start, you should have a clear understanding of your research topic. When the main idea is clear to you, it becomes easier for you to search and read about that specific topic. It saves your time and protects you from writing irrelevant and extra information not related to the topic of your research. You should be clear about the main concepts and keywords of the topic, the areas you will be focusing on, and the most useful type of source for your research, be it data, idea, or method-based.

Step 2: Finding Sources

This is the first and most important step in the literature review. To look for the most suitable and reliable sources that can give information about our selected topic of research. Some of which are discussed below,

1. Academic Journals are research papers that have accurate and recent research material.
2. Books that have theories and ideas discussed in detail.
3. Conference papers in which the latest research is published.
4. Government or Institutional Reports can give you statistics for your research.
5. Dissertations or Theses provide you with the pattern and material of others’ studies, so that you can have an idea when starting your own writing.

You can take help from Google Scholar, JSTOR, Scopus, or any university library website. When searching for sources, use clear keywords such as and, or, and not. Do not forget to keep a record of your sources from the start so that you can write all of them in the end without missing any.

Step 3: Critically Evaluate the Sources

To just summarise the sources is not a critical review, but you need to analyse how trustworthy the work is, what methods are involved, what opinions it has, and what it says about your topic. Keep in mind not to miss what the main pieces of advice and answers are, whether the methods used are suitable or not, the limitations and weaknesses of the research study, its similarity with others’ work on the same topic, and in what ways it supports or denies your study.

For example, there are two studies on climate change education, and both have opposite results so our study should tell what the reasons are that made this difference. The difference could be because of number of people, location or due to the methods used in the research. 

A serious literature review makes your research strong by showing that you have studied both the positive and negative aspects of the study, which were available, that helped you in finding patterns, differences, and add information regarding the topic which others have missed previously. 

Step 4: Identify Themes and Trends

When you are done reviewing sources, then next step is to write a literature review. Writing a literature review is all about finding common outlines in the studies you read. You should organize your information by themes instead of dates to make your research look more meaningful.

There are some common ways to organize your outlines;

1. Write whatever new research you find regarding your topic that was not written anywhere previously.
2. Arrange your study by topic instead of date or author.
3. Comparing your studies with other studies based on different research methods.
4. You look for how other theories and different thinking aspects of others can explain your research topic easily.

For example, if you are doing literature review for your dissertation and the topic is social media marketing, so you’ll arrange your themes somewhat this way:

The effect of social media on client actions, brand engagement on social media platforms, and ethical conflicts in digital marketing. 

It shows how other different studies are connected with each other and gives your literature review a clear structure by collecting these types of themes.

Step 5: Structuring the Literature Review

To make your piece of research easily understood by others and grasp what you want to convey in your research, you’ve to follow a clear structure for literature review. Following is the format that you’ve to follow, but you can make changes in your structure accordingly.

• Introduction: This includes description and importance of your topic. Write the potentials of review, what you have included and excluded. Explain what method you’ve chosen for the research, be it arranged on the basis of time or on the basis of themes, or any other sort of method.

• Main Body:  In the main include the studies you examined based on themes. Talk about the different opinions of other writers and whatever new you want to include in your study that is not discussed by the previous researchers. Also, what are the new trends going on?

• Conclusion: In the end, summarise the main understandings of the study that you gained. Explain a new piece of study that you have added to your research, which was not discussed previously by any other researcher. Make your readers understand how this literature review helped you in shaping main idea and method of research.

Step 6: Writing the Literature Review

Start writing the literature review once you’ve collected all the sources. Keeping in mind that using a clear formal language will give your writing an organized look, also do not list all the sources one by one in your writing; instead, write the research material of all the researchers together and then link their information.

For example, Smith (2020) says teacher feedback is very important in online learning, but Jones (2022) believes that peer interaction is more effective. However, both studies agree that student participation is essential, meaning that group activities can improve online learning results. 

This is a clear example of how you can write the opinions of other writers altogether and relate them to each other, instead of writing them separately one by one, which will only make your work more confusing for readers.

Step 7: Review and Revise

The last step in literature review writing is proofreading your work and editing the mistakes. This will not only improve your writing but also check whether the content is clear, logical, and free from all the errors. All the references mentioned are written correctly with a correct format. All the paragraphs should be about your research topic, no irrelevant information should be discussed. The material written throughout your writing should be analytical and refrain from explaining things too much. To improve your writing, always take feedback from your supervisor, it will help you in long run.

Example of a Literature Review Paragraph

Here is an example of a literature review paragraph, and it can clearly be seen how the writer has put the opinions of others in a single paragraph, maintaining the analytical tone of the study.

According to recent research, Artificial Intelligence is playing a very important role in the field of education. Brown (2020) says that AI can help make learning more personal by studying student data. Instead, Green (2021) points out that privacy problems might stop schools from using these tools. White (2022) adds that AI learning systems only work well if schools have the right technology and teachers are trained. These studies show that AI can be very useful, but still there are some difficulties when using it in classrooms.  

Common Mistakes to Avoid

Refrain from committing these common mistakes which, are as follows, when writing a dissertation literature review:

1. Do not just describe or summarise any study; instead, analyse them and connect them with each other.
2. Write your review according to a clear structure and theme.
3. Do not ignore the topics in your research that need to be discussed in detail.
4. Site all sources correctly.
5. Rely more on new studies rather than focusing on old research.

By avoiding these mistakes, you can write a very professional literature review.

Final Thoughts

If you want to write a professional literature review, learn the skill of doing it first. It shows that how clearly you understand research work of others. A strong written literature review proves that you understand main discussions of your research topic, easily find out and write whatever was missed by other researchers in their study, and by doing all this, you can easily build a strong base for your own research.

If you follow some basic steps that are all discussed above, such as searching the sources, then critically evaluating them, identifying themes, and most importantly writing a literature review with a clear structure, you’ll no doubt end up writing a well-organized and professional literature review.

Never forget that a literature review is not just the summary of others’ research, but through it you can show your ability to think analytically and give to your research and how you can link it with your own study.
