Google is offering to broker sales of books online for publishers. “The new offering would allow people to sign in and purchase immediate, browser-based access to books, Google said on its site. Purchasers would not, however, be allowed to save a copy of the book to their computer or to otherwise copy pages from the book. Google is marketing the new program as the first of several tools intended to help book publishers boost their revenues, though it was unclear Monday how many had signed up. Pricing would remain entirely at the book publisher’s discretion.”
