The document discusses what a review of literature is and how to write one. It notes that a literature review aims to show that the researcher has read and understands the main published work on a topic. It should provide a critical discussion and synthesis of relevant literature, linked to the researcher's objectives. When writing a literature review, the researcher must decide what to read, take clear notes, and structure the review with an introduction, linked arguments, and a conclusion. A good literature review evaluates previous research and identifies areas for further study in a formal, objective style.
