 == Termination of copyright transfers == 

 It would be good to see something about the copyright transfer termination sections of this act. That's the right of an author (or their heirs) to essentially reclaim a copyright under certain circumstances, even if they've signed it away ""in perpetuity"". The Superman article alludes to the termination rights at 56 years for older works, and there are beginning to be news articles about the termination rights at 35 years for works published on or after Jan 1, 1978 (since they'll come due in 2013).
