WebStasher
I just can't say enough about how much I like using WebStasher (http://www.webstasher.com/index.html).
This is a tool for saving copies of web pages for yourself, which are then organized, and searchable, within your IE environment. Once the pages are saved, they are available offline as well.
I've been using this since an early beta, and I can tell you, the experience with them has been incredible. Originally, it didn't fully save the page (with graphics) to be available offline. It had some bugs here and there, like most products. But every time I emailed in a suggestion or bug report, I had responses (usually from more than one person) within a day's time, so I feel confident that if I ever needed "support" it would be there.
If you do web based research, or like to save articles you find for later perusal (offline even), you owe it to yourself to check it out.
