Citation Managers

Zotero collects all your research in a single, searchable interface. You can add PDFs, images, audio and video files, snapshots of web pages, and really anything else. Like other citation mangers, Zotero has features that allow you to Collect, Organize, Cite, Collaborate, and Sync your database across devices/platforms.  Zotero download is available for Mac, Windows, and Linux.
