Referencing is a way of acknowledging the sources of information that you use to research your assignments. You need to provide a reference whenever you draw on someone else's words, ideas or research.
You should also provide references for any graphic information you use. Films, television programs, personal communications and online sources also need to be referenced.
Not referencing other people's work can constitute plagiarism. See our guides on Understanding and Avoiding Plagiarism.
Preferred referencing styles vary between schools (or even courses), so check your course outline (usually found on Moodle). If you can't find any information there, try the Faculty website or school offering your course. If they don't indicate a preference, ask your tutor.
Below you will find short style guides to three systems: Harvard, APA and Footnote-Bibliography.
There are a number of other referencing styles available. For information on other styles, try an internet search or look for published guides in the UNSW Library.
