Zotero
From Brock University's Digital Humanities Compendium
Zotero [zoh-TAIR-oh] is a free, easy-to-use tool to help you collect, organize, cite, and share your research sources. It lives right where you do your work—in the web browser itself. Zotero also has a standalone version that can work with browsers other than Firefox.[1]
The Simulating History Lab at Brock University has created this tutorial to help digital humanists get started with Zotero.
