Brian Alt, over at ezine-tips, has a nice multiple part introduction to copyright law for ezines, that's worth a look if you publish an ezine. While he's not a lawyer, he does have experience with the form, and does a very nice job of explaining fundamentals from a practical stance. Here are the parts: Introduction, Part 1, Part 2, Part 3.
[A similar article, called Copyright For The Webmaster, covers many of the same aspects of copyright on the web as the ezine article, but adds a little more about javascripts and digital watermarks.]
