You need to reference all information sources you use. To do this, you just need to insert a citation in your text and then expand on this in a footnote or full reference list at the end of your work. The exact way you need to do this depends on your referencing style.
Each department of the university uses a particular referencing style. Use the drop-down box below to find out which referencing style your department uses. You'll find each department listed alphabetically, with the referencing style given in brackets.
Once you've selected your department and style, press 'Go' to be taken to guidance for your style!
