Lawrence Lessig: Fighting for Our Human Heritage

If you believe in the public domain, if you want any work to become part of it ever again, and if you want to keep most books and films from rotting away before they can be reprinted -- support Lawrence Lessig and pray for his victory in Eldred v Ashcroft, and that the Sonny Bono Act (permitting copyright to be extended indefinitely) will be declared unconstitutional.

Wired has a good article about him and his fight.
