What is one purpose of a literature review?

A literature review serves several essential purposes in the context of research, and one of the most significant is to assist in planning future research. By reviewing existing studies, researchers can identify gaps in the current knowledge, understand the methodologies that have been used previously, and establish a theoretical framework for their own work. This process helps ensure that new research is built on a solid foundation, avoiding unnecessary duplication and allowing researchers to refine their hypotheses and research questions based on what has already been discovered in the field.

The literature review informs researchers about how others have approached similar topics, which can guide them in selecting appropriate methods and frameworks for their own studies. By contextualizing their research within the existing body of knowledge, researchers can make informed decisions that enhance the validity and relevance of their work, ultimately contributing to the advancement of the field.
