References are indicated by a superscript number (1, 2, 3) within the text, usually at the end of the sentence (or, if clearer, directly after the word or phrase to which it relates). This is accompanied by a corresponding footnote at the bottom of the page. Footnote references should always end with a full stop.
To create a footnote in Word, go to the ‘References’ header in the top menu. Ensure your cursor is where you want to add your reference and click on ‘Insert Footnote’.
This will insert a superscript number alongside the text of your work and at the bottom of the page where you write your citation.
