I couldn't help but post this. The Authors Guild, the folks suing Google, have written up talking points so that you can back them up if you happen to go to a dinner party this weekend (their words, not mine).
Listen to this little gem.
"Google is digitizing countless texts, your books, in their entirety -- every sentence, every carefully chosen word -- without your permission."
It sounds like you should tack on, "and taking lunch money from small children" onto that sentence.
Lessig weighs in on the matter with a nice article over on his blog.
