One of the most frequently asked questions I get is regarding how to find the value of books that don’t have an ISBN. I don’t know of any websites that buy these types of books back directly. Often-times, however, the ISBN just isn’t easily found, or may not be on the book at all. I’ve put together a tool that will allow users to search for books by Author, Title, and the published year. This should allow casual users to find the ISBN and hopefully find a good place to sell their books to somewhere. In the event that nobody is buying the book, it will also display prices from Amazon marketplace and an estimate of how long it may take to sell.

The tool is now available at http://bookscouter.com/pre-isbn
