What's My Book Worth?

A Brief Guide To Evaluating and Describing Old and Rare Books

The State Library does not offer appraisal services, but has put together this brief guide to help you evaluate and describe old and rare books. Remember that library personnel are here to serve you as an information resource and offer many materials from our various collections, as well as public access to the Internet.


There are at least eight facts a book dealer needs to know about your book:

  1. Author (last name first)
  2. Title of the Book
  3. Place of Publication (Items 3, 4 & 5 may be on the title page or reverse of title page.)
  4. Publisher
  5. Date of Publication
  6. Size (height of book)
  7. Kind of Binding (cloth, leather, etc.)
  8. Condition of Book (see list of industry standards below)


It is important to both collectors and dealers that you accurately describe your book’s condition using industry standards.

As New - is to be used only when the book is in the same immaculate condition in which it was published. There can be no defects, no missing pages, no library stamps, etc., and the dust jacket (if issued with one) must be perfect, without any tears. (The term As New is preferred over the alternative term Mint to describe a copy that is perfect in every respect, including jacket.)

Fine - approaches the condition of As New , but without being crisp. For the use of the term Fine there must also be no defects, etc. If the jacket has a small tear or looks worn, this must be noted.

Very Good - can describe a used book that does show some small signs of wear—but no tears—on either binding or paper. Any defects must be noted.

Good - describes the average used and worn book that has all pages or leaves present. Any defects must be noted.

Fair - is a worn book that has complete text pages, including those with maps or plates, but may lack endpapers, half title, etc., which must be noted. Binding, jacket (if any), etc. may also be worn. All defects must be noted.

Poor - describes a book that is sufficiently worn that its only merit is as a Reading Copy because it does have the complete text, which must be legible. Any missing maps or plates should still be noted. This copy may be soiled, scuffed, stained or spotted, and may have loose joints, hinges, pages, etc.

Ex-library - copies must always be designated as such, no matter what the condition of the book .

Book Club - editions must always be noted as such, no matter what the condition of the book .

Binding Copy - describes a book in which the pages or leaves are perfect, but the binding is very bad, loose, off, or non-existent.

Dust jacket - in all cases, the lack of a dust jacket should be noted if the book was issued with one. If the book has a dust jacket , save it. Even if torn, the book’s value is enhanced by it.

Foxed or Foxi - describes a book that is not bound in original binding.

Uncut Edges - means that the edges of a book are untrimmed by machinery; and Unopened means that the untrimmed edges have not been opened by hand.

Autographed - If a book has been signed by the author, it is important to note this.

Repaired - Describe what has been repaired.

An example of a description prepared using industry standards:

Scott, Joseph. A Geographical Description of Pennsylvania, Philadelphia,
Cochran, 1806. 5 1/2 inches, leather, Good, with original dust jacket.


You can get a general indication of the value of your book by consulting the following references. Note that this list is not all-inclusive, but provides you with a starting point in your quest. The rare book trade is subject to fluctuating values based upon collector interest, availability, condition of the book, and of course, supply and demand.
