You do realize that it was the US court system that put the library-of-the-world version of Google Books on ice, correct? Larry & Sergey wanted a hippy "share all the books to everyone" view of this. The court said no, do what the book publishers say.

While you're mentioning the Internet Archive, you might also recall that our advertised purpose is to digitize all the world's knowledge :-)

I just had a chat with our book guy today about OCR corrections using captchas, one of our volunteers suggested it. We expect to scan 500,000-700,000 books this year.
