What does “good” condition mean?
Brand New: direct from the publisher.
As New: describes a book that is in the same perfect condition as when it was issued by the printer.
Fine: not quite as crisp as an “as new” book; has possibly been handled in a bookstore.
Very Good: shows some small signs of wear — but no tears — on either binding or paper.
Good: describes the average used book that has all pages or leaves present.
Fair: describes a worn book that has complete text pages.
Poor: describes a book that is sufficiently worn but still fine as a reading copy.
Ex-library is a book that has been cancelled from a library system. It will have marks indicating this on the spine and back cover.
