Official name of Google’s new project: Google Print
From the FAQ:
Can I read an entire book online?
If the book has no copyright restrictions and is considered public domain, then you can browse through the entire book. For books still under copyright, you’ll only be able to see a few pages or, in some cases, only a few sentences. In general, Google Print is designed to help you discover books, not read them from start to finish. It’s like going to a bookstore and browsing – only with a Google twist.
