The review of literature, also known as a literature review, is a critical analysis and synthesis of the existing research on a particular topic. It involves identifying, evaluating, and synthesizing published works, scholarly articles, and other relevant sources of information related to the research question.
The purpose of a literature review is to provide an overview of the existing research on a topic, identify gaps in the literature, and provide a foundation for the research that follows. It helps researchers to understand the current state of knowledge on a particular topic, identify key themes and concepts, and identify areas where further research is needed.
A literature review typically involves a comprehensive search of databases, academic journals, and other sources of information related to the research topic. The sources are then evaluated for their relevance, credibility, and quality, and the key findings and themes are summarized and synthesized in the literature review.
The terms “background” and “literature review” are often used interchangeably, but they have different meanings and serve different purposes in a research paper.
The background section of a research paper provides contextual information about the research topic, including its history, significance, and relevance. The background section sets the stage for the research question and provides the reader with the necessary context to understand the research question and the research that follows. The background section typically includes a brief overview of the research topic, its historical development, and any relevant contextual information that the reader needs to understand the research question.
On the other hand, the literature review is a critical analysis and synthesis of the existing literature on the research topic. The literature review summarizes, synthesizes, and evaluates the key ideas and findings of previous research studies relevant to the research question. The literature review aims to identify gaps in the literature, highlight areas of agreement and disagreement among researchers, and provide a foundation for the research that follows.
In essence, the background section provides contextual information about the research topic, while the literature review critically evaluates the existing literature on the topic. The background section is typically shorter and more general than the literature review, while the literature review is more detailed and specific. Both sections are important for providing context and understanding of the research topic, but they serve different purposes in a research paper.

Conducting a literature review involves a systematic and comprehensive search for relevant literature on a particular topic. It is essential to search for literature from different sources, including academic journals, books, conference proceedings, and grey literature. The following steps can help conduct a literature review:
Step 1: Define the research question
The first step in conducting a literature review is to define the research question. It sets the foundation of the entire review process, providing focus and direction for the analysis. The research question guides the search strategy, shapes the structure of the review, helps to evaluate the relevance of the sources of information, and determines the analysis and synthesis of the literature. It ensures that the review is focused on a specific area of interest and avoids being too broad or unfocused.
Step 2: Identify relevant literature
Identifying relevant literature is the second step in conducting a literature review. A comprehensive search should be conducted using various search engines and databases. The search should be based on the keywords related to the research question. It is important to ensure that the search is comprehensive and includes all relevant literature.
Step 3: Evaluating the quality of the sources
Once the sources of information have been identified, the next step is to evaluate the quality of the sources. This involves assessing the reliability, validity, and relevance of the sources. This can be done based on the following criteria:
Step 4: Identify key themes
Once you have analyzed the sources, the next step is to identify key themes that will guide the structure of your literature review. These themes should be based on the research question and objectives and should reflect the main findings of the literature review.
Step 5: Group studies by theme
After identifying key themes, the next step is to group studies by theme. This will help to ensure that the review is structured logically and that all relevant studies are included.
Step 6: Synthesize and analyze the literature
Once the studies have been grouped by theme, the next step is to synthesize and analyze the literature within each theme. This involves critically evaluating the findings of each study, identifying research gaps, and drawing conclusions about the state of research on the topic.
Step 7: Organize the literature
After evaluating the quality and relevance of studies, the next step is to organize the literature into meaningful categories or themes. This can be done by identifying commonalities or patterns in the research and grouping studies accordingly. The literature can be organized chronologically, thematically, or based on the methodology used in the research. We have discussed how to organize a literature review in the following section in detail.

There are three common approaches to organizing a literature review: chronological, thematic, and methodological. Here’s a detailed explanation of each approach:
The chronological approach involves organizing the literature review by the order in which studies were conducted or published. This approach is useful when examining the historical development of a research topic or when tracing the evolution of research ideas over time. It can be particularly useful when the research question involves understanding the historical development of a topic, or when the research question is focused on a particular period.
The thematic approach involves organizing the literature review around key themes or concepts that emerge from the studies. It can help to identify patterns and trends in the literature and to highlight areas of consensus or disagreement among researchers. This approach is useful when the research question is broad and complex, and when there is a need to synthesize multiple studies with differing methodologies and findings.
The methodological approach involves organizing the literature review by the research methods used in each study. This approach is useful when the research question involves evaluating the strengths and weaknesses of different research methods or when the research question is focused on a particular research method. This approach can help to identify gaps in the research, highlight areas of controversy, and provide insights into the limitations and opportunities of different research methods.
It is important to note that these approaches are not mutually exclusive, and researchers may choose to combine them to best address their research question. For example, a researcher may choose to organize their literature review chronologically and thematically, to provide a comprehensive overview of the historical development of a topic and to highlight key themes and concepts that have emerged over time. Ultimately, the choice of approach will depend on the research question, the available literature, and the goals of the literature review.
Writing a literature review involves synthesizing the collected literature and presenting it in a coherent and meaningful manner. Here’s how to write a literature review appropriately:
