You can use Zotero to insert references into a Word document, generate a bibliography at the end of your document and format it in the citation style of your choice.
When you install Zotero Desktop on your computer, the Zotero tab is automatically added to the toolbar in Word. If it is not there, go to the Tools menu in Zotero Desktop to install the MS Word plugin.
Please note: You must use Zotero Desktop to use the Zotero citing tool – it will not function with Zotero Web.
