Zotero automatically formats your references into whatever citation style you (or your professors) prefer: MLA, Chicago, APA...
In addition to the citation styles that come standard with Zotero, you can also download hundreds of other additional styles.
There are mistakes in Library catalogs and databases! Whatever Zotero imports will ultimately be in your bibliography, so check the output for errors -- correct any inside Zotero, then rerun your bibliography so that it will be permanently fixed.
Create a simple bibliography by dragging any list of items from your Zotero Library and dropping it anywhere that you can type: a Word Document, a Google Doc, your email. Or Right-click any list of references and select ‘Create Bibliography from Selected Items…’ to create a new file of automatically formatted citations.
Zotero can automatically format parenthetical (in-text) or footnote citations directly in your paper in Microsoft Word.
If you are using Google Docs, add the Chrome Extension, Zotero Connector and it will appear in the Google Docs menu.
