Evaluating your Old Book

With your book in hand, ask yourself the following questions. To determine the true market value of a book, or any other collectible item, an appraisal may be necessary.

  • What is the condition of the book?
  • Is it a first edition? A first edition is the first time a book is printed by a publisher. Not all first editions say the words "First Edition" on the title page.
    • Your book is probably not a first edition if there is more than one publication date, or if the word "printing" appears with the publishing information, for example "2nd Printing" or a series of numbers such as "2 3 4 5 6 7 8 9." The lowest number shows which printing it is.
  • Who is the author of the book?
  • What is the full title?
  • When was it published? The date might be on the back of the title page. Check to see if there is more than one date, or if the date says "copyright," "reprint," or "edition."
  • Who is the publisher? More than one publisher can publish the same book, and there can be American and English editions by different publishers. When a book is no longer under copyright, anyone can publish it. The exact name of the publisher is important, especially if there is no date on the book.
