You probably already know that you can bookmark your favorite Web sites in your browser. But if you want to go a little bit further and organize your Web searches even better, here are four tools you can use for free:

Clipmarks Save anything - content, videos, messages, etc. - and save them to your Clipmarks. You can share them with others, too, if you want.

Diigo is the prima donna of research tools. You can use it to save your favorites, highlight information, archive, bookmark, annotate, and access your information from anywhere.

Evernote can save anything for you, even screenshots; then it will organize them for you. Couple of ideas you can use Evernote for? Try creating a detailed vacation itinerary with maps, ticket information, and tourist spots, or how about keeping all those notes from that business meeting right where you can find them next time (and you can even take pictures of the whiteboard!).

Zotero is a Firefox extension that you can use to collect, organize, and even cite your Web research sources. You can store PDF files, make detailed notes on a Web page, and make a bibliography.
