This page explains how to find ISBN number on a textbook.

Take a textbook, and look at the back side of the cover. You should see a bar code in the bottom right corner. Above it, there is a ten digit number, maybe with a letter, like this: 0471975230, or 0-13-490012-X. Just type it exactly how it appears in the book.
