The legal issues of Copyright are confusing, and just about as complicated as the US tax code. Most of us want to do the right thing about getting permission, but we aren't always sure what that "right thing"might be.

It isn't enough by itself but should give you an idea of what needs to be done. The link is listed in the Copyright sidebar on this blog, as well as here"
