The authors guild, and several other authors are suing google. I think it only proper. I mean, why flood the earth with books and information that could benefit the world? There is always a chance that your book that went out of print 50 years ago suddenly roars back into public demand. Then the dollars are going to come rolling in.
That last sentence was dripping with irony, just in case it wasn't apparent.
I personally wrote to the guild and expressed my thoughts on the matter.
