5.3 Numerical referencing

Another convention for citing references in your main text is to use either numbers in square brackets or superscripts, where the numbering starts at the beginning of the report and increases sequentially throughout. These would appear as reference [1] or reference¹. Each number must refer uniquely to a given source, detailed in a list collected together at the end of the review, under the heading ‘References’.

The following example shows a book, a journal article and a website collected together in the same numerical reference list.
