This guide covers only the basics of referencing. If you want to find out more, you might like to look at some other sources which cover the issues included in much greater depth. Much of the advice included here is based on that given in the following text, held in all of the University of Bedfordshire campus libraries:
Pears, R. & Shields, G. (2010) Cite them right : the essential guide to referencing and plagiarism, 8th edn. Newcastle: Pear Tree Books.
The examples included in this online guide have used the Harvard system, but there are various other systems available. A few others are listed on the referencing schemes page here. Find out which method your department recommends, and follow the conventions. Remember that the main priority is to be consistent in your referencing style. If you are unsure as to which referencing style you are expected to use, ask your lecturer for guidance.
You can find further guidance on the main page for this help section. There are also a number of books and e-books on carrying out research that include detailed chapters on referencing methods.
