From the Official Google Blog, “When we launched Google Print, our goal was to make it easier for users to discover books. Now that we’re starting to achieve that, we think a more descriptive name will help clarify what our users can do with it: namely, search the full text of books to find ones that interest them and learn where to buy or borrow them…We want to make all the world’s books discoverable and searchable online, and we hope this new name will help keep everyone focused on that important goal.”
