Google's job is to help people find information. Google Print's job is to make it easier for people to find books. When you do a Google search, your results now include pointers to those books whose contents, stored in the Google Print index, contain your search terms. For many books, these results will, like an ordinary card catalog, contain basic bibliographic information and, at most, a few lines of text where your search terms appear.
We show more than this basic information only if a book is in the public domain, or if the copyright owner has explicitly allowed it by adding this title to the Publisher Program (most major U.S. and U.K. publishers have signed up). We refer people who discover books through Google Print to online retailers, but we don't make a penny on referrals. We also don't place ads on Google Print pages for books from our Library Project, and we do so for books in our Publishing Program only with the permission of publishers, who receive the majority of the resulting revenue. Any copyright holder can easily exclude their titles from Google Print -- no lawsuit is required.
Seem not so controversial for me for the moment.
