Enter Google, the hip, incredibly profitable corporation whose motto is "Do No Evil." Google doesn't like the copyright laws as they have existed for centuries. Google wants the rights to store all the books in the world in its Google Library program, and the company doesn't want to pay for that right.
Copyright? No problem. Google cites "fair use," but it isn't using 400 words; it plans to digitize whole libraries and make them available piece by piece. Google is formidable. Google has brilliant public relations people and clever lawyers and connections in important places.
I'm not getting the controversy here, hasn't Amazon been doing this for awhile now?
