Cover Peeling - At very good level or below, indicates the edge of the cover laminate is peeling, making the laminate visible with a tape-like appearance.

Edge/Spine Wear
Spine Wear - At very good level or below, indicates a crease on the spine suggesting the book has been read. At good level or below, this may indicate a curvature to the spine, suggesting the book has been left open for some time.

Page Wear
Page Crimping - At very good level or below, indicates a small number of pages may have been crimped and then flattened. At good level or below, an area up to 1/4in from the edge of some pages may be crimped, abraded, or dog-eared.

Pages Uncut - At very good level or below, indicates some pages may have not been cleanly cut by the publisher.

Used Markings
Remainder Marking - At condition level fine or below, there may be a black or red mark on the edge of the pages indicating it is used. At condition level very good or below, there may be a marking on the inside or rear cover barcode.
Store Marking - At condition level very good or below, this may indicate a hand-written price on the inside cover. At condition level good or below, this may indicate a stamp on the inside cover or edge of the pages indicating it was purchased form a used book store. There may be a price tag on the rear cover which is difficult to remove without damaging the cover.
Library Markings - At condition level good or below, this may indicate the book has stamps or stickers on the outside and/or inside cover and/or page edges, indicating the book was formerly property of a school or public library. The cover may be partially or fully laminated. There may be a card holder attached to record check-out records.
Owner Markings - At condition level good or below, indicates a prior owner may have written their name or brief note on the inside cover. In rare cases, the owner may have laminated the book.
Page Writing - At acceptable level, indicates writing or highlighting on the content pages.

Dust Jacket Notes
No Jacket - At condition level very good or below, indicates a hardcover book missing its dust jacket.
Dust Jacket Damage - At condition level very good or below, indicates a torn or otherwise damaged dust jacket, which would otherwise result in a reduced condition grade. The dust jacket is provided for completeness and may be discarded by the purchaser.
Irrespective of wear, we expect each book sold to be pleasant to read.
