Citation examples

Standard citation

Every citation should be labelled within your text by using a number in brackets (1).
You should insert the citation number directly after a source is referred to in your text, even if this is in the middle of your sentence. It is acceptable to place a citation number at the end of a paragraph, if the entire paragraph is referring to the same source.

The first item you cite is allocated number 1, the second item is allocated number 2, and so on throughout your piece of work.

Once a source has been allocated a number, this number is used again if you refer to the same source at a later point in your work.

When to include page numbers

You should include page numbers if you quote directly from the text, paraphrase specific ideas or explanations, or use an image, diagram, table, etc. from a source.
