This is good.
href="http://www.getfirefox.net/">Firefox now has
an extension that makes it simple to store all your bibliographic
information from online research.

It is at release candidate 3 stage now, well-developed and
fully functional. It is called
href="http://www.zotero.org/" rel="tag">Zotero.
It is bundled with the “
href="http://www.mozilla.com/en-US/add-ons/campus/">Campus
Edition” (the best thing since ramen noodles) of Firefox, but
it can be installed easily into any version on Linux, OS X, or even
Windows machines.
From an article at

Insider:
For purposes of bona fide research and
turning incompletes into passing grades, Zotero is a big something.
Zotero, which resides within the browser, can store the author, title
and publication fields, and export the information as formatted
references.Zotero is a production of the Center for History and New Media at
George Mason University. Some of its funding has come from the United
States Institute of Museum and Library Services and the Andrew W.
Mellon Foundation.
It is a polished piece of work, another instance of quality programming
in the free — libre — open-source software arena. I tried
it with a nearly random search at Medline and it worked well.
You can associate tags and notes with each reference, then
export the entire thing. This is going to save a lot of
people a lot of time.
