A literature review is an important component of any academic research project. It involves reading, analyzing, and summarizing existing research in order to provide an overview of the current state of knowledge on a specific topic. In this blog article, we will discuss the different approaches to writing a literature review, the best time to do it in the research process, the structure of a literature review, and the key steps to follow when writing one. By following these tips and guidelines, you will be well on your way to compiling an effective and comprehensive literature review for your next academic study.

What’s a literature review

The purpose of a literature review is to review the current state of knowledge on a particular topic, identify gaps in the existing research, and suggest areas for future exploration. A literature review should include a synthesis of relevant information from multiple sources, such as published journal articles, books, dissertations, conference proceedings, and other scholarly materials. It should also include an evaluation of the quality and relevance of the sources used. By completing a thorough literature review prior to beginning your own research study, you can ensure that your project is well-informed by the latest findings in your field.

Different approaches

There are several common approaches to writing literature reviews. The most common approaches include narrative reviews, systematic reviews, meta-analysis, and qualitative studies.

Narrative reviews take stock of the relevant literature on a particular topic by summarizing key findings from multiple sources.

Systematic reviews are more comprehensive and involve searching for evidence using predefined criteria and then synthesizing the results into one comprehensive document.

Meta-analysis combines data from multiple studies to draw conclusions about larger trends or relationships between variables.

Qualitative studies focus on understanding individual experiences or perspectives related to a specific research question or phenomenon.

When it is best to do it

Providing an overview of the existing literature on a particular topic helps to identify gaps in knowledge and areas for further exploration. Literature reviews are often required when writing a dissertation, thesis, or research paper in order to ensure that the work is based on up-to-date evidence and previous studies. Literature reviews can also help to inform decision-making processes by providing an overview of the current state of knowledge on a particular subject. By critically examining the existing literature, researchers can better understand how their own work fits into the existing body of knowledge.

  2. Background: a brief history and context of the topic.
  3. Objectives: the purpose and goals of the literature review.
  4. Research methods: how the sources for the review were selected and found.
  5. Summary and evaluation of sources: a synthesis of the findings from the sources and an assessment of their relevance and quality.
  6. Synthesis of findings: a compilation of the key findings from the sources into themes or categories.
  7. Conclusion: a summary of the main points from the review and suggestions for future research.

Key steps to do it
