Zotero is a free, open-source citation management tool that allows you to easily collect, manage, cite and share research sources.
To get started you will need to:
1)To use in Word: Download the Zotero Desktop Application available for Windows, Mac, and Linux.
2) To use in Google Docs: once you've downloaded Zotero, you'll also want to download the Zotero Connector to add content with a single click.
The Zotero Connector is available for Chrome, Firefox, and Safari. If you plan to access items from a mobile device, you may want to download the Zotero Bookmarklet which will allow you to save them to your online Zotero library. If you plan to use Microsoft Word or LibreOffice, open Zotero and install the citation add-in by selecting Edit > Preferences choosing the Cite option, and selecting the Word Processors tab. Select the add-in you wish to install.
If you've installed the Zotero Connector for Chrome or Firefox and have the Zotero program installed, a Zotero menu option will automatically appear in Google Docs.
