For those of you who are unaware, galley proofs are books that are complete in just about every way. They bear the mark “Galley Proof” or “Edit Sample” or something similar. Galley proofs are primarily used to get into the hands of those who will review them and provide the immortal quote. Many books have a quote from a famous author or organization. The way they get those quotes prior to publication is to send galley proofs as a free offer to get their feedback before the final print of the book with those quotes on them.
