Literature reviews

The purpose of a literature review is to provide a comprehensive overview and analysis of existing research and scholarly articles related to a specific topic or research question. It serves several important functions within academic and research contexts: situating your research within the broader academic landscape, identifying gaps, evaluating the quality of existing research, synthesising information from multiple sources and organising it in coherent manner, supporting your research methodology and generating new insights through a critical analysis of existing literature. 

Overall, a literature review helps researchers to understand the current state of knowledge, identify research gaps, and build upon existing scholarship. It provides the necessary background information and context for your own research, ensuring that your work is grounded in existing literature and contributes meaningfully to the academic discourse.

The structure of a literature review can vary depending on the requirements of the specific discipline, the purpose of the review, and the preferences of the author. However, there are generally common elements that you can include in your literature review. Here is a typical structure:

Introduction:

  • Provide an overview of the topic and its significance.
  • State the purpose of the literature review and its scope. 
  • Define any key terms or concepts that will be used throughout the review.
  • Inclusion and exclusion criteria:

Explain the criteria used to select the literature for your review (e.g. age groups, study design, context, geographical scope, publication date range, language, etc.). Justify the rationale behind your criteria to ensure the literature you include is relevant and appropriate for your review.

Literature search process:

  • Describe the search methods and strategies you used to identify relevant literature (e.g., databases, search terms, reference lists, citation tracking, etc.).
  • Provide details about the number of initial search results and how you narrowed down the literature to the final set included in your review.

Themes or sub-topics:

  • Organize the literature according to themes or sub-topics related to your research question.
  • Present the main ideas, theories, findings, and arguments from each study or group of studies.
  • Identify commonalities, patterns, and gaps in the literature.

Critical analysis:

  • Evaluate the strengths and limitations of the studies included in your review.
  • Assess the methodologies, sample sizes, data sources, and research designs used in the literature.
  • Highlight any inconsistencies, contradictions, or controversies among the studies.

Synthesis and discussion:

  • Synthesise the information from the reviewed studies, focusing on the key findings and trends.
  • Identify any gaps or areas where further research is needed.
  • Discuss the implications of the literature for your research question or topic.
  • Provide a summary of the current state of knowledge and how your research will contribute to it.

Conclusion:

  • Summarise the main points of the literature review.
  • Emphasise the key findings and their implications.
  • Suggest directions for future research based on the identified gaps.

References:

Include a list of all the references cited in your literature review, following the appropriate citation style (e.g., APA, MLA, Harvard, Vancouver... ). You could use citation management software to format your references according to a specific referencing style within the text and in the list of references. 

Remember, this is a general structure, and you should adapt it to the specific requirements of your discipline and the purpose of your literature review. Always consult your instructor or research advisor for any specific guidelines or expectations.
