• "Referencing is a standard practice used in academic writing to show your reader which ideas you have gathered from other sources and where those ideas came from" (UniSA, 2018, p. 2).

    There are many referencing styles out there, with different professions and disciplines preferring specific styles.  Referencing styles include 'author-date' (e.g. APA, Harvard), 'footnote' (e.g. Chicago, Legal  Citation), and 'notational' (e.g. IEEE) methods. Formatting rules on how you structure your citations, what bibliographic elements to include and which punctuation markers you use will also vary from one style to the next, so it is important that you find out which style you are required to use in each of your courses, and follow the relevant referencing style guides.

    While many referencing styles exist, the purpose of referencing remains the same regardless of what style you are required to use.
