Isn't this a bit like preaching to the choir? At this point I would think the only people who oppose this are either the Google-overlord-fearing folk (who can never be appeased anyway), or other companies who are suddenly alarmed that they didn't have the balls to make a first move in this space.
To the latter - tough cookie. To the former I would like to ask this: other than the shadow of the Big G, what do you truly see wrong with Google Books?
There are some issues with the legality of it. Gojomo (http://news.ycombinator.com/item?id=870926) summarized it better than I will, most likely. Although I'm for the process itself, the legal side seems a tad shady to me. I realize it would be a logistical nightmare to attempt to get permission from all authors, but the opt-out clause with such a short time frame didn't seem entirely fair. I'm glad that they gave an extension to it, and that the repercussions of the settlement are being looked at harder. Once again, I'm definitely for such a project, and I'm not a google-fearer, but something of this magnitude deserves some careful examination.
