Terms of Digital Book Deal With Google Revised
The amended settlement dropped in the eleventh hour. Here's a redline version and here's the related memorandum with the procedural details. The best news coverage is the New York Times story; the best blog coverage is Danny Sullivan's. I've just completed a first pass through the amended settlement, tweeting all the way.
The biggest change is that the class of affected books has been dramatically reduced, although not at all in the way I was expecting. Books registered in the U.S. are still in, as are books published in Canada, the U.K., and Australia. That change should largely take foreign non-Anglophone books out of the settlement entirely. There are a number of other tweaks to the definitions to deal with specific classes of works (e.g. comic books).
