This video explains what a literature review is in an academic context. It defines a literature review as a critical recap of existing research on a topic, using a real-world example to illustrate its purpose and importance. The video outlines three main reasons for conducting a literature review: to understand what is already known and how it's been researched, to provide a critical overview of existing knowledge and show how new research fits in, and to identify gaps in current knowledge to contribute something original.
