How can I find the ISBN number of a book?
The International Standard Book Number (ISBN) is a 10-digit or 13-digit number that uniquely identifies books and book-like products published internationally. You can find an ISBN number in several places on a book. Look on the copyright page located in the front of the book near the title page. ISBNs are also often found on the back cover of the book sometimes near the publisher's barcode. Newer barcodes will begin with the numbers "978." If you don't have the book, try looking up the ISBN using www.worldcat.org.
