A great starting point is our Referencing LibGuide, where you can navigate between a variety of styles and resources.
There is a very useful resource called 'Cite Them Right' that is available through Library Search. In the ribbon at the top you can choose what kind of information source you are are citing and then you can change the style, as shown in the picture, even though the default style is Harvard:
With this information, you can reference manually in any of the above styles, to begin with. Cite Them Right will show you the structure of a full reference for each different source of information and will provide examples as well.
If you are using Endnote to reference, the style can be automatically changed from Endnote (please see FAQ 177912) or from Word at any time by clicking on the Endnote tab in the blue ribbon in Word and then clicking on 'Style'. Remember that your Endnote library has to be open while using the 'cite while you write' function in Word.
