Ms. Peets, I remember teaching the case of Robertson v. Thomson Corp more than once, and thinking that the good news is that Heather Robertson won, and the bad news is that Heather Robertson won. This is simply because, as you said and as I think we all predicted at the time, publishers would just react by ensuring that every time they signed a contract to a freelancer, they would get all the rights.
