Zotero to the rescue!

If you haven't yet heard of Zotero, watch this. It's a free, open-source bibliographic tool that operates from within Firefox, but can be accessed on- or offline. Zotero can "see" bibliographical material on webpages--say, within an online library catalogue, or on an Amazon page for a book recommendation--and grab it, store it, and export it properly formatted for a few mainline bibliographical styles with the click of a single button.

Highlights:

• It can also be used as a web archiving tool, as it can capture "snapshots" of pages
• you can annotate snapshots with highlighting and notes that are saved to your hardrive along with a copy of the page. Wow. That is way cool.
• it organizes information into an adaptable, drag-and-drop, hierarchical folder system - again, better than Endnote
• you can put the same references into different "collections" without copying and pasting and risking not updating
• you can create links between references/files
• you can add as many separate notes as you like, and be as long-winded as you like, and attach them to whatever reference/snapshot you like
• you can attach other files to the references/snapshots -- e.g., other snapshots, or pdfs, or your essays...
• your library can be portable and not confined to one computer
• you can export and import in all the major formats (BibTex, RIS, Endnote, etc.)
• you can export properly formatted citations in some styles (Chicago, MLA, for example)
• it can and will replace Endnote, which I really don't want to have to shell out $300 for to get updates that fix problems instead of offering better features.

Also, a perfect tool for blog-cruising of wanna-be public intellectuals...
