How to rate a book's condition

SpineValue standard 2026-10-08-v2 · Published October 8, 2026

Grade the physical copy you hold. An ISBN identifies an edition; condition describes this copy. Printing, signatures and rarity need separate evidence and do not erase defects.

Inspect before choosing a grade

  1. Check both covers, spine and binding: rubbing, tears, creases, loose hinges and repairs.
  2. Leaf through pages: completeness, loose/missing pages, stains, writing, highlighting and folded corners.
  3. Check the dust jacket, inserts and included media when applicable. Disclose a missing jacket even if the book itself is sound.
  4. Check odors, moisture, mold and pest damage. Quarantine mold-contaminated books rather than offering them for sale.
  5. Write specific defects in Condition Notes. Choose the lower grade when a material defect contradicts the higher description.

These are schematic inspection examples, not photographs or evidence about any listed book.

Unrated

Not inspected yet. Inventory can remain Unrated. Choose a rating after inspecting the physical copy.

No automatic marketplace eligibility while Unrated.

Like New

Essentially pristine, clean and complete, with sound binding and no writing or meaningful wear. Check the jacket and included materials; disclose exceptions.

Very Good

Light wear, complete pages and sound binding. Disclose minor rubbing, small inscriptions, marks and light jacket wear.

Good

Noticeable wear, but intact and readable. Describe annotations, stamps, creases, jacket defects and repaired damage.

Acceptable

Heavy wear or markings while still usable. Describe every significant defect, repair and missing accessory.

Poor

Major damage or serious usability concerns. Explicitly describe failed binding, loose/missing pages, moisture damage and other material defects. Never imply a damaged copy is complete.

Useful condition notes

“Light spine rubbing; name written inside front cover; text pages unmarked; jacket has a 1 cm edge tear.”

“Frequent highlighting in chapters 2–4; binding sound; included workbook is missing.”

Describe facts, not vague claims such as “great for its age.” Put acquisition cost, customer information and internal reminders in Private Notes, never Condition Notes.

Record your inspection
