Oxford is a citation style that uses footnotes at the bottom of the page, unlike in-text citation styles such as APA. This guide is a brief description of the Oxford citation style described in:
Style Manual for Authors, Editors and Printers, 6th edn., Canberra, ACT, AGPS, 2002.
Before you write your Reference List or Bibliography, check with your lecturer/tutor which style they prefer you to use and refer to the instructions included with your assignment.
Information about why you need to reference is available in the Academic Integrity at VU guide.
