An ISBN is a unique identifier for a book that helps libraries and booksellers keep track of books. ISBNs can be extended to include the book price, making it easier for booksellers to read price from a barcode. If you are a small publisher or a self-publishing author, at some point you might want to deal with ISBNs.
