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.
For general information on referencing, including an explanation of different citation systems, and guidance on citing specific types of publication, see our Citing references guide.
For advice on using references in your work, and how to use them to support your arguments, consult the guidance on the Study Advice website or make an appointment with them.
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.
