This week the US Congress could vote on a major copyright bill that would radically redefine the legal use of creative work. “The Senate might vote on HR2391, the Intellectual Property Protection Act, a comprehensive bill that opponents charge could make many users of peer-to-peer networks, digital-music players and other products criminally liable for copyright infringement. The bill would also undo centuries of “fair use” — the principle that gives Americans the right to use small samples of the works of others without having to ask permission or pay.”
