The University of Wolverhampton uses Cite Them Right as the preferred referencing style for all new students (levels 3, 4 and 7). The Library has an online interactive guide available here: Cite Them Right. Cite Them Right supports referencing systems including Harvard, Vancouver, APA, MLA, OSCOLA and MHRA.
Referencing correctly is important to demonstrate how widely you have researched your subject, to show the basis of your argument and conclusions and to avoid plagiarism. This involves noting down the source for any information that you access, recording in a systematic manner where you got the information from.
