Google wouldn't be that crazy, surely. Imagine the copyright outrage, the legal fees, and the obvious need to track down authors all over the world.
Why such a fantasy would cost them $125M at least!
that is nothing compared to what they could gain
They can't, really. This case focused at times on the fact that you could never actually see the papers on the website. Google wants to display content of books, so this case is inapposite.
Yeah you're right that's why I said for search purposes. Still, I'd like to see if the music industry would let me keep an archive of all of their songs (without paying for any) just for sound analysis.
