How Much Is My Book Worth?
I often receive email asking if I can give a value for a book. Without seeing and researching the book, I genuinely have no idea — condition and edition are so critical to any appraisal that I would never consider giving a value sight unseen. And to be frank, I don't provide appraisals for free. But here is some guidance to help you find the answer yourself.
Intrinsic Value vs. Market Value
The intrinsic value of a book and its retail price can be two completely different things. To use a simple example: suppose you have a family bible that has been handed down through eight generations. Old bibles are remarkably common, and while a few are genuinely valuable, the vast majority are essentially unsaleable at any price. Your treasured family heirloom might be worth less than five dollars on the open market.
A more complex example: a book by a well-liked but retired professor of linguistics at Queen's University in Kingston, Ontario. This book might sell for a reasonable price in a Kingston bookstore if one of his old students happens in. Try selling it in Tucson, Arizona, and the chances of it selling at all — even for a pittance — are small. Market is everything.
And another: a book on military history that is genuinely rare but has relatively low demand. What sets the value — rarity or demand? It depends on how patient the seller is, and how specialized their market is. A military specialist with a large and educated customer base can ask considerably more than a general bookseller who carries only a few military titles.
The Three Factors That Actually Matter
There are only three factors that determine a book's value: condition, scarcity, and demand. Age has nothing to do with it. A fine first edition of James Joyce's Ulysses from 1922 will bring vastly more on the open market than an ordinary family bible a hundred years older. To a book dealer or serious collector, a book from the 1800s is not old. Old means 1650, or perhaps 1750 — after 1850, books tend to get considerably more common.
Also worth noting: the terms "vintage" and "antique" have no meaning in the book world and are not used.
Condition Is Critical
The single variable most likely to affect your book's value is its condition, and whether it is complete. By complete, I mean that the book has its original dust jacket intact. While a jacket may seem an unimportant part of a book, it is the most fragile element and thus the most likely to be missing or severely damaged. The resulting rarity of intact jackets makes them, in many cases, worth more than the book itself.
A book with missing pages is almost always worthless, regardless of age. The only exceptions are books with full-page colour plates that can be individually rescued, and a handful of immensely valuable early printed books.
Retail vs. Wholesale
Are you researching for insurance or estate purposes? Then you want retail replacement value. Are you trying to figure out what you can actually sell the book for? That is a different question entirely.
From a bookseller's perspective, they want to know how quickly they can turn a book around. A book worth $500 that won't sell for several years may be less interesting to them than a $50 book for which they already have a customer waiting. And cheap books take just as long to process as expensive ones — so on a $5,000 book you'll get a much higher percentage of retail value than you will on a $15 book.
How to Research the Value Yourself
Search ABEBooks or Biblio for the same edition in comparable condition. If copies are currently for sale, you'll see at what prices they are being offered. Make sure you have exactly the same edition — this matters enormously — and that the condition is truly comparable. See How to Describe Book Condition for help with condition grades.
The Rare Books and Manuscripts Section of the American Library Association maintains an excellent resource called Your Old Books, which answers many common questions about book values and what to do with a collection. Biblio also has a useful guide to getting a book appraised.
When to Get a Professional Appraisal
If you can't find comparable copies, or if the book appears to be genuinely rare and valuable, find a knowledgeable bookseller who specialises in that type of book and get a proper appraisal. Be prepared to pay for it. A specialist has spent years learning their field and invested considerably in price guides, bibliographies, and auction records. That knowledge has real value.
To find a qualified appraiser, the Antiquarian Booksellers' Association of America (ABAA) and the Antiquarian Booksellers' Association of Canada (ABAC) both maintain directories of member dealers, many of whom offer appraisal services.
Good luck.
