Citing & Referencing


Citing and referencing your sources is essential when you’re writing your assignments, because failure to do so is plagiarism. There are lots of different citation styles used in DCU; check your course handbook to find out which one you're required to apply. Each citation style has a style guide that shows you how to use it. 

This page provides links to style guides we recommend you bookmark for quick reference, where to find help, and details of how to get started with Zotero - an open source reference manager that can help you out when you have lots of sources to keep track of. 


Check out our video which explains some of the principles behind citing and referencing - which together are your best means of avoiding plagiarism.

DCU Library subscribes to Cite Them Right Online, an excellent resource which will help you to reference correctly and avoid plagiarism.
