Compare Sites to Find an Average Price
Visit a Web site like Amazon.com or Alibris.com to compare the price of the book you are interested in researching. You will find information about the condition of the book, as well as if it is a first edition copy, signed by the author, or contains a handwritten message from the author.
Examine the book, as the condition of the book is very important in determining its value. Books that do not contain markings, discoloration, loose or missing pages, or a torn or loose spine, receive a higher value. Remember: many considerations are taken into account to value a rare book.
Compare various Web sites carrying the same book you want to value and find an average price. (Be sure that each copy is in the same condition.) Check out: Dis-dis.com, Housingworks.org, Goldeneyebooks.com or Bookfinder.com.
Decide if you want to keep the rare book or sell the book at its current value.
