Zotero - Collect, Organize, Cite, and Share References  

Zotero, is a no-cost bibliographic management tool that runs on the Windows, Mac X, and Linux operating systems. Zotero can: 1) organize references in multiple folders; 2) store references and files on Zotero's web site; 3) format in-text citations and post-text references according to many bibliographic styles; 4) display references on a public web page; and 5) import metadata from library subscription databases and public web sites. 

Setting up a free Zotero account gives you:

1.  unlimited storage space on Zotero’s servers for your metadata (information about your sources, e.g., author, title,   publisher, etc., including your text notes);

2.  up to 300 MB of storage on Zotero’s servers for PDF and image files. You can purchase more file storage space--$20/year for 2 GB, $60/year for 6 GB.

You can choose to just store your source metadata on the Zotero servers and NOT store any files there.

On any computer where you install desktop Zotero, you can configure Zotero to sync your desktop data (and files, if you choose) with the content stored on Zotero’s servers.
