What is the purpose of a literature review?

A literature review serves the essential function of summarizing, analyzing, and synthesizing existing research on a specific topic. This process involves evaluating various studies, theoretical frameworks, and findings that have already been published in the field. By doing this, a literature review establishes a foundation for understanding the current state of knowledge regarding the topic at hand. It identifies gaps in the research, highlights trends, and may also lead to new insights or directions for future investigation.

This comprehensive overview is not about critiquing individual writing styles or presenting personal opinions about literary works; rather, it focuses on systematically organizing and discussing the contributions of other researchers. Therefore, the literature review becomes a critical element in academic research, helping to contextualize new research within the broader scholarly landscape.
