If you have not been following the Google settlement, Judge Denny Chin has just provided an extra four months to figure it out. If, as an author, you want to opt out of the settlement you now have until September 4, 2009.
The gist of the settlement, as far as I can tell, is this Google asserts the right to scan all books as a part of the Google Library Project, The Authors Guild assumes the rights to represent all owners of printed works in opposing this rights grab.
You can object, or opt out of the settlement--otherwise you are assumed to opt in. The settlement will disperse $45 million dollars to those whose books were digitised without their consent (about $60 per book). Google is then allowed to use any books from this list that are not in print, unless otherwise instructed by the rights holder.
