Zotero is a free citation management program that helps you collect and organize your research information.
When you open Google Docs in a browser that has a Zotero Connector installed, you will see a Zotero option added to your menu.
To add a citation to your Google Doc:
1. Choose "Add/edit citation" from the menu. If you don't already have Zotero running on your computer, you will be prompted to do so.
2. Next, you will be prompted to choose your citation style from a pop-up dialog box.
3. When you're ready to save or publish your Google Doc, go to:
Note: If someone views your active Google Doc without having the Zotero Connector installed they can still read and/or edit, but active citations will show up as links leading to URLs.
