Our condition rating scale is fairly simple:
A - Used - Like New Almost new, no or very, very slight creases to the spine, no marks on the pages and very little wear to the cover.
B - Used - Very Good: A well-cared-for book that has seen limited use but remains in great condition. The book is unmarked, and undamaged.
C - Used - Good: Still in a good condition, spine creased and corners of the cover may be damaged.
D - Used - Acceptable: Well read, spine or cover worn or damaged, pages may be yellowed or stained.
