favorite copyright website

I have a favor to ask all of you out there in listserv land. I will be giving a presentation on copyright resources on the Web for an event we are holding for National Library Week. I've come across some good ones, and noted several from this list. But what are your favorites? Are there some with particularly good graphics, solid information, or other things that might be of interest to people in a medical school?

Feel free to respond to me off list at the address below, if you're bothered by list clutter.

Thank you very much,
