Microsoft Word's Referencing tool is an easy-to-use tool that assists with creating citations, bibliographies and reference lists for your documents. A brief introductory guide can be found here.
It is important to note that while the output from the Microsoft reference tool will generally be accurate it is not error proof. For example you may put information in the incorrect field in which case it will display incorrectly. It is important therefore to always check your citations and reference list for accuracy before submitting your work.
There could also be slight differences between different editions of a Referencing Style. We use the Harvard Anglia Ruskin Referencing Style 6th ed. (version 6.1.2 April 2019), while Microsoft Word uses the 4th edition. However this should not affect your citations and referencing as the basic underlying rules are the same for both editions.
