Barbara Feldman:

I'm researching copyright, fair use and music piracy for an upcoming Surfnetkids column, and I came across this great multi-part article titled Copyrights and Copying Wrongs: an Education World series on copyright and fair use. It answers questions about what can and can't be freely used in lessons, presentations, reports, and on school websites. It also gives an overview of public domain works.

It's an excellent article, but I probably won't include it in my column because I try to focus on sites for kids to use (not sites for teachers.) Of course, sometimes these two audiences overlap, so we'll see.
