Cite While You Write (also known as CWYW) allows you to access EndNote from within Microsoft Word. You can use it to insert citations into the text and it will automatically build a bibliography from these citations.
EndNote should be installed after you install Microsoft Word to add the EndNote menu to the top ribbon.
EndNote is designed to insert citations while you are writing your document (Cite While You Write), but sometimes there are good reasons NOT to use it and create an "independent bibliography" at the end of a document instead:
We acknowledge the Australian Aboriginal and Torres Strait Islander peoples as the first inhabitants of the nation and acknowledge Traditional Owners of the lands where our staff and students, live, learn and work.
