The International Study and Language Institute (ISLI) recommend using the APA 7th (American Psychological Association) referencing style.
Whenever you refer to another person's work in your own essay, dissertation or article you must acknowledge them and give full details of your source. You risk being accused of plagiarism if you fail to do so.
APA referencing is a variant on Harvard style. Many of the conventions are the same, with brief author-date citations in brackets in the body of the text and full citations in the reference list. It is usual to include a reference list only rather than a bibliography in APA style. Citations for websites are also slightly different, with no need to include an access or retrieval date unless the page content is likely to change over time.
First, refer to your Department's referencing guide linked above. You will find additional examples and explanations in the APA Publication manual below, and further examples of specific references e.g. government publications using the 'Cite them Right' guide or websites linked below. If you can't find the answer in either of the guides below, please speak to your Academic Liaison Librarian.

When you do your dissertation you could consider using EndNote to manage your references. This bibliographic management package can be used to store references, and then insert the citation in your Word document, automatically building the bibliography for you in the correct style.
