Broaden your knowledge in your particular research area
The most important function of the literature review is to ensure you read widely around the
subject area in which you intend to conduct your research project. It is important that you know
what other researchers have found in regard to the same or similar questions, what theories and
models have been put forward, and what gaps exist in the relevant body of knowledge. The
literature review also helps you to understand how the findings of your study fit into the existing
body of knowledge. Finally, a thorough literature review helps to ensure that you are an expert
in your area of study
