There are two main referencing styles: the author-date (or Harvard) style and the numeric style.
There are variations on each type, so it is important that you familiarise yourself with the specific style used in your school. Information about referencing styles is normally available in degree programme handbooks, but some schools produce more detailed guidelines in a separate document. Many schools have adopted a variation of the Harvard style known as Harvard at Newcastle, which is available in EndNote.
If you are writing for publication, you need to familiarise yourself with the house style of your target journal. This information is normally available in the ‘Instructions for Authors’.
You will find more information about referencing styles on the Library website.
