Notice: As of 7/7/25 we will be reducing the descriptive information for common and less valuable items. While we always aim to provide accurate and concise information about the book you are buying, the rate we are able to list vs the backlog of stock we have to offer has grown too great. It no longer makes sense for us to spend the same amount of time on a $10 as it does a $100 or even $1,000 book. As such, descriptions will be shortened to the bare bones on common items. This will be formatted as:

Publisher, City of Publication, date of copyright. Number of pages, size. Condition: Book Condition/Dust jacket condition if applicable. Any major pertinent flaws I. E. a tear to the dust jacket, soiling, etc.

Example:

Garden City, New York, 1938. [IX], 8vo. Condition: G/G. Boards bowed, tear to the front joint of the jacket.

We will always mention whether a book has writing within it beyond common marks such as a former price, stock number, owner name or initials, etc., OR major condition issues. 

Condition will be between Fine-Poor in line with The Antiquarian Booksellers Association of America(ABAA). Below you will find a helpful guide for determining the condition of a given book.

Fine, (abbreviated F) Fine is very close to As New in condition, except that the book may have been been previously opened or carefully read.

Near Fine (abbreviated NF) A book approaching Fine (or As New) but with a couple of very minor defects or faults such as a former owner name(FON) on the front free end paper(FFEP).

Very Good (abbreviated VG) This is a book that shows signs of prevoius ownership and use, but it?s still very nice copy. Approaching near fine with two or three minor flaws or defects.

Good (abbreviated G) Possibly the most confusing book condition for the layman. A good condtion book will show significant wear including the potential for tears in the dust jacket, wear on the edges of the wraps or boards as well as the textblock. Specific issues should still be noted. A good condition book should still have all pages and a fully intact cover.

Fair is a book with noticable wear. Some non-essential pages such as the Front Free End Paper(FFEP) or Rear Free End Paper (RFEP) may possilby be missing but the entire text and all plates should be still present. A Fair condition book isn?t typically considered collectible condition (except in cases where scarcity is such a factor that a better copy isnt commonly available). Fair condition books are still servicable reading copies.

Poor A book with significant wear and faults. A poor condition book is still a reading copy with the full text still readable. Any missing pages must be specifically noted.

Ex Library: In traditional book description guidelines, this is a book condition unto itself. The statement that the book was removed from library circulation historically indicated that the book had no collectible value due to certain standard practices of libraries such as ink stamps asserting ownership and uniquely durable tape binding the dust jacket to the rest of the book. That old standard has relaxed some over the years.

Books with a condition of VG or below will be within that range, the book you purchase could have minor issues in line with it's rating that are not mentioned in the description and are common of used books such as bumping, creasing, prices or owner inscriptions. An additional condition report may be requested by the buyer BEFORE purchase.
