Referencing is where you refer to a source in your writing, such as a book, journal article or newspaper article. When you reference you need to properly record the information you have used - this way whoever is reading or marking your work will be able to find the original source. There are many different referencing styles but one of the main ones is the Harvard referencing style which is demonstrated on this page.
There are two parts to referencing. The first part is when you add references within the main text itself (in-text citations). This is a shortened version of the full reference that goes in your reference list, usually just containing the authors surname and year of publication. For example:

If you mention the authors name then there is no need to include this in the brackets, for example:
Robinson (2001) suggests that.......
The second part of referencing is the Reference List. This includes all full references for all of the sources you have cited in your main body of work, arranged alphabetically.
