Mendeley is a reference manager and a citation tool which can help organise your citations and references.
Instructions can be found in the Mendeley Quick Guide.
This guide also contains information on how to use Mendeley Reference Manager, the Mendeley Web Importer Extension for browsers, and the Mendeley Citation Plug-In Tool for Microsoft Word.
It is important to review the references and citations for mistakes before you submit assignments. Check your references against the Referencing Tool and the APA 7th edition Referencing Guide.
