If a book is like a baby, the Advanced Reader’s Copy (ARC) is its ultrasound.
ARCs are uncorrected proofs or galleys released by the publisher before the book goes to press for a complete printing. These proofs are printed in softcover and they still may have some unexpected typos. Used for promotional purposes, ARCs are distributed to book buyers at large chains and reviewers at magazines and newspapers three to six months before the book is officially released.
Here are the “ultrasound” images for Is It Night or Day? The “due date” (release date) for the baby is March 16, 2010.
