This document discusses the importance of proper referencing in academic writing. It explains that referencing gives credibility to work, shows the breadth of research, and avoids plagiarism. There are two main components of referencing - in-text citations that refer to sources in the body of the work, and a reference list at the end that provides full details of all sources. Several common referencing styles are described, including Harvard, Vancouver, MLA, APA, and Chicago styles, with examples provided of how to format references for books, journals, and websites in each style. The key difference between a reference list and bibliography is also explained.
