I am not a techie by any means but I love organizing information. A couple of tools I like are: del.icio.us bookmarks which allow you to organize bookmarks by adding tags and notes. Its also great because you won’t be confined to your own computer to use the bookmarks since you access them via a website where you set up a free account. I set up a few different delicious pages at work and they really come in handy for new employees.
I also just got turned on to Zotero which I love. You can organize your research and save several different things like: links to pages of interest, bibliographic information, and pictures. Once you sign up for Zotero you can easily add the citation information for articles and books with just a click.
Finally, Harvard University has just added the firefox extension: LibX. I read about MIT using this and thought it was a great idea. You simply add the extension to your firefox toolbar and you can easily find items in the OPAC. One of the best features is that it allows you to instantly link to the Harvard catalog from Amazon or other on-line booksellers. This is a really great tool and more public libraries should consider setting this up.
