    1. How to write a literature review

    2. What is a review article? A review article is a type of secondary literature that talks about previously published work. “Review articles give an overview of existing literature in a field, often identifying specific problems or issues and analysing information from available published work on the topic with a balanced perspective.” 6 Article types that journals publish: A guide for early career researchers - Kakoli Majumder - Available at: http://www.editage.com/insights/6-article-types-that-journals-publish-a-guide-for-early-career-researchers

    3. Types of review articles Today, we’ll understand how to write a literature review. Systematic reviews Literature reviews Meta-analyses

    4. What is a literature review? A literature review is a critical summary of all the published works on a particular topic. It analyzesspecific issues. It identifies trends in research. It points out research gaps in existing literature. How a literature review helps scientists and readers • Scientists are able to: • Learn about developments in the field • Find gaps in research • Identify new topics of research • Readers are able to: • Form an idea about the current state of understanding on a topic • Decide whether to read each article individually

    5. How to write a literature review • You can write your literature review using one of the following approaches: Chronological Thematic

    6. The chronological approach Describe each work in succession, starting with the earliest available information. TIPS for using the chronological approach • Use this structure when you want to focus on how ideas or methodology have progressed over time. • Group and discuss your sources in order of their publication date. • Record the research and developments in each group. • Check how the field has developed over the years. Do all studies discuss a common topic? • Example: how models for treatment methods for skin cancer in children have developed over a specific period Vector designed by www.freepik.com

    7. The thematic approach Organize and discuss existing literature based on themes or theoretical concepts you feel are important to understanding the topic. TIPS for using the thematic approach • Remember that you need to do much more than summarizing each study. • Analyzeexisting knowledge on the topic with regard to certain important issues. • Draw the readers’ attention to new angles or perspectives. • Start listing citations you may include in your paper.

    14. Final checklist (1/2) The topic must be interesting to you; it should also be well-defined and important to the field. Choose the right topic Check the literature you have chosen Monitor the papers you have chosen to review, make changes to your bibliography, if required; prepare a complete reference list. Write interesting bits of information or ideas as you read so that you don’t miss important points when writing the review. Take notes while reading Decide whether you should use a thematic or chronological approach, based on the amount and type of material you have. Decide the format of your review Keep the focus specific and interest general While you focus on a specific topic, make sure your review is also relevant to a broader audience who may want to know more about the field.

    15. Final checklist (2/2) Cover the main findings in the reviewed field, include topics that are most debated, add your own thoughts instead of reporting what has been said. Analyze critically, don’t summarize Use a flowchart to map the flow of ideas in your literature review, and ensure that readers get a critical overview of research in the field. Get the structure right Seek feedback from colleagues and peers, and get more perspectives from senior colleagues before submitting your literature review for publication. Rely on feedback Avoid sounding as though you are overly critical or in favor of previous research; objectively present the strengths and weaknesses of previous studies. Be objective It is not necessary to only include the latest studies in your review; include older papers that made a high impact or that discussed the topic you are interested in.
