When you find material to use for essays and assignments you must reference (cite) it correctly. Whilst studying at CDU you are expected to write to an acceptable academic level. You will need to develop skills displaying academic integrity, which means being honest about your ideas and sources. Referencing, when done correctly acknowledges the work of others and will prevent you from accusations of intellectual theft and plagiarism.
There are many referencing styles (APA, CDU Harvard etc): ensure you know the style required for your course. The library has examples of how to reference books, articles, web sites etc for the the different referencing styles.
It allows the reader to follow an idea, using the details provided, to locate the original publication. This could be because the reader is interested in the topic or because they wish to verify the details of the quotation, making sure the author hasn't been taken out of context.

It's important to familiarise yourself with the required referencing style early. This is so you know what details to record from the material you find so that you can actually reference it. You can download a template here to help you record the required details.
