TechLearning reports on a really handy Internet research tool. Use have to use Firefox a the browser to use this, but it's well worth it. For researchers, I dare say that Firefox is a far superior web browser to Internet Explorer. It's worth downloading Firefox and using it when you research on the web.
In a nutshell, Zotero looks like it does what the comment function in Microsoft Word does, i.e., allow you to put little comment bubbles beside the text it relates to. But then it can export all those bubbles as a report. This looks great for briefing cases and writing articles.
Here's a brief excerpt from an article discussing Zotero:
Zotero (zotero.org) is a free, easy-to-use Firefox extension to help you collect, manage, and cite your research sources. It lives right where you do your work - in the web browser itself. Zotero integrates these tools, bringing you the benefits of an online tool and the security of storing all of your information locally for access at anytime. I have been looking for a research tool where I could keep my notes, attachments, and links right in the browser.
