Also, here are some issues worked out in court recently, with full text available at http://www.googlebooksettlement.com
"The settlement, if Court-approved, will authorize Google to scan in-copyright Books and Inserts in the United States, and maintain an electronic database of Books. For out-of-print Books and, if permitted by Rightsholders of in-print Books, Google will be able to sell access to individual Books and institutional subscriptions to the database, place advertisements on any page dedicated to a Book, and make other commercial uses of Books. At any time, Rightsholders can change instructions to Google regarding any of those uses. Through a Book Rights Registry ("Registry") established by the settlement, Google will pay Rightsholders 63% of all revenues from these uses.
"Google also will pay $34.5 million to establish and fund the initial operations of the Registry and for notice and settlement administration costs, and at least $45 million for cash payments to Rightsholders of Books and Inserts that Google scans prior to the deadline for opting out of the settlement."
