There are three main reasons for referencing:
• to show which previous works your own work is drawing on
• to distinguish your own thoughts from those of others and to avoid suspicions of plagiarism
• to enable the reader to check out your sources or to delve deeper into the subject
Different disciplines have developed different ways of writing references and created various styles, such as Harvard, Oxford, APA, IEEE and Vancouver styles. Your supervisor should be able to tell you which is the most common and desirable style within your discipline.
Once you have chosen a reference style, the library Referencing group can help with questions regarding specific references. You are welcome to email questions to email@example.com.
