A literature review in a research paper is a detailed summary and critical evaluation of existing studies related to a specific topic or research question. It helps researchers understand what has already been studied, what theories or methods have been used, and where the research gaps lie. In short, it builds the foundation for your research by connecting your work with prior academic knowledge.
In most research papers, the literature review is placed after the introduction and before the methodology section. It acts as a bridge between your research question and the methods you use. It is important in:
- Establishing the context and background of the research
- Identifying research gaps
- Supporting the research framework or hypothesis
- Avoiding duplication of previous studies
Example Of A Literature Review In A Research Paper
Here is a literature review sample in the research paper that serves as an excellent example for your understanding:
Topic
The impact of AI-based tools on student creativity.
Literature Review
Artificial Intelligence has emerged as a marvellous tool in the educational and academic landscape. Through its innovative nature, it has helped students and researchers with learning, getting tasks done effectively, and extracting better academic content. However, its integration into education has raised concerns all over the world as the creativity skills of students have been put at risk.
According to Brown et al. (2020), AI-driven tools have stifled the originality of students and eroded their critical thinking skills by offering automated essays and content generation.
Similarly, Johnson (2020) observed an over-reliance on AI tools for repetitive tasks such as user-generated content. Moreover, as their use increases, students plagiarise much of the content in their academic essays, blurring the lines between human-written and AI-produced content. This has raised ethical concerns over academic integrity as it creates a false sense of achievement in the minds of students.
Despite these findings, there are significant gaps in their research. These studies primarily focused on AI’s impact on student creativity in isolation without considering broader themes of educational curriculum and teacher guidance. Moreover, little to no research has been conducted as to how different AI tools affect the innovative capabilities of students. By evaluating prior research, we aim to provide a comprehensive understanding of the implications and benefits of the role of AI within the context of proper teacher guidance and well-defined educational curricula.

Types Of Literature Reviews
Different types of literature reviews are used depending on the research purpose, scope, and methodology. Below are the most common ones:
| Type of Review | Description |
|---|---|
| Narrative or Traditional Review | Provides a general overview of the topic, summarising key theories and findings without a strict methodological approach. |
| Systematic Review | Involves a structured and comprehensive search for all relevant studies on a topic, followed by a critical appraisal and synthesis of results. |
| Scoping Review | Maps the existing literature in a particular field to identify key concepts, gaps, and research trends. |
| Meta-Analysis | Combines statistical data from multiple studies to identify overall trends and patterns in quantitative research. |
| Theoretical and Methodological Reviews | Focus on analysing theories, models, or research methods to evaluate how they have evolved and been applied in past studies. |
How To Write A Good Literature Review For Your Research Paper
Before you write, it is necessary to understand how to write a literature review for a research paper and the steps needed to conduct a literature search.
- Conduct a literature search
- Select the sources
- Identify themes and gaps
- Write your literature review
- Edit and proofread
Step 1: Conduct A Literature Search
The most imperative part of a literature review is defining the topic and subject for your research paper. This also involves stating your research question so that relevant studies that address the research question can be sought for analysis and comparison.
Moreover, it is also important to mention the timeframe of your research paper so that readers and researchers can understand if your focus is on historical research work or recent developments.
After defining your research question and scope of work, start finding sources and knowledge that support your work by using online databases and primary and secondary sources of information.
This means conducting a research literature review from the internet to paper and going through reliable sources such as library catalogues, articles, published research papers, journals, Google Scholar, JSTOR, and EBSCO by using keywords that align with your work.
Step 2: Select Sources
Then comes the second most important part of your literature review. Analysing the relevance and quality of your academic sources is necessary so that irrelevant pieces of information can be discarded. To select the best sources, start by organising similar papers, articles, and research projects with themes and keywords that are related to your research question and topic.
Then, proceed to compare every source to establish its relevance and credibility. Here are some questions to consider while evaluating each source:
- What are the key findings of this research?
- What are the primary concepts being discussed?
- What are the theories and methods of data collection?
- What arguments arise from conflicting perspectives?
- How has the researcher addressed the limitations of his research?
- What are the strengths and weaknesses of this research work?
- How does this work relate to and differ from other literature in this field?
After selecting credible sources that best align with your research question, take notes for your writing process, and do not forget to add citations to avoid plagiarism.
Step 3: Identify Themes & Gaps
A literature review for a research paper must have a clearly defined outline that discusses recurring themes, patterns, core concepts, the methodological approaches used in research, and any disagreements and areas lacking research.
By discussing these, you can establish the need for new research that is being addressed by your work, and any influential theories that can change the direction of the research in the field.
Step 4: Write Your Literature Review
Then comes the main part of your literature review: the format of a literature review for a research paper. Like any other academic writing, it comprises three major parts that synthesise and analyse the collected information accordingly. Let’s discuss how a literature review is written:
Introduction
The introduction sets the stage for your literature review and critically highlights the main topic or research question to be addressed. An opening statement briefs the readers about the purpose, objective, and scope of your literature review.
An organisational framework of how you found the sources, how they will be included in your work, and why your work is important to the field of research is also a vital part of your introductory paragraph. Last, conclude your paragraph with a thesis statement that outlines the main argument to be addressed in the research paper.
Body
The body provides a thorough understanding and analysis of existing literature, the relevant themes, concepts, and the methodologies used for research. Start by discussing the recurring trends and patterns in the literature, the common themes that are addressed, and the areas of research that have been left untouched.
Instead of paraphrasing other researchers, try to add your own opinions and interpretations. Additionally, evaluate the strengths and weaknesses of the prior research and how to overcome the challenges for future researchers. You can also discuss how your review contributes to filling the gaps. Moreover, use transition sentences and phrases to create a smooth transition and flow between paragraphs.
Conclusion
The final part of writing a literature review concludes your evaluation by mentioning the key findings and results from the literature and their relevance to the broader academic field. Also, a good conclusion in a literature review explores the implications or discrepancies of the findings for future research and discusses potential directions and tips for research in the field.
Step 5: Editing and Proofreading
After you have written your first draft, proofread and edit your content to ensure that it is error-free, factually correct, grammatically coherent, and well-cited. You may revise it as needed and make any changes. It may be helpful to get feedback from peers, instructors, and researchers in your field to support a more critical analysis.
How Long Is A Literature Review For A Research Paper
If you are writing a research paper or dissertation, then you must be aware of the length of your section that covers your literature review. There are several factors that determine the length of your literature review for a research paper, some of which are:
- The overall length of your research paper
- The complexity of your topic or subject.
- Your instructor or journal studies provide the specified guidelines or instructions.
Additionally, your literature review should comprise 20 to 30% of your research paper, enough to provide a comprehensive analysis of the existing research on your topic, but not overshadow your original research paper and work.
Difference Between A Literature Review And A Research Paper
A literature review sets the foundation for new research by evaluating and analysing already existing knowledge, but on the other hand, a research paper provides new knowledge by conducting original research. Moreover, they differ from each other in various aspects, which are as follows:
| Research Paper | Literature Review | |
|---|---|---|
| Objective | The main purpose is to present original research and findings based on new data and analysis on a topic or subject. | The purpose of a literature review is to analyse prior research to address gaps and contribute to new knowledge in the field. |
| Focus | Its primary focus is new knowledge. | It focuses on existing knowledge. |
| Structure | It involves an abstract, introduction, literature review, methodologies, results, and a conclusion section. | It involves an introduction, main body, and conclusion. |
| Tone | The tone can be both argumentative and persuasive when presenting new findings. | The tone is objective and informative. |
| Sources | It mostly uses primary sources such as interviews, experiments, and focus groups to collect data. | Secondary sources are used by researchers while conducting a literature review, such as already published articles and papers. |
