Speaking as an author whose book is available to "preview" at Google Books...I'm wondering how I can opt in.
Having looked over the preview, I was okay with it. It revealed just enough to give a taste and hopefully encouraged people to buy it (or not buy it if they wouldn't like it, and then complain about it in online reviews because it's not scholarly enough or they don't get the humor). Sort of like the "read inside" function at Amazon.
Clearly I need to read up on the settlement.
