Always check with your school which referencing style you need to use and the exact requirements they expect, as these may differ from the information outlined on these pages.

References and citations: an introduction

Referencing is the acknowledgment of the sources you used when producing your piece of work. Referencing correctly is important to demonstrate how widely you have researched your subject, to show the basis of your arguments and conclusions, and to avoid plagiarism.

You need to give the person reading your assignment enough information to find the sources you have consulted. This is done by including citations in your work and providing a list of references.

Citations
Whenever you use someone else's ideas, either by putting them into your own words (paraphrasing) or by quoting directly, you must show this within the body of your work. This is known as a citation. The format will vary depending on the referencing style you use.

References
At the end of your assignment you will need to provide a list of references - full details of the sources you used when writing your assignment. Your references may take the form of either a reference list or a bibliography.

Referencing activities
Knowing when and where to reference is key to avoiding plagiarism.
