What are ISBNs? ISBNs are 10 or 13 digit codes identifying specific editions of a book. They're sometimes written with hyphens. Examples: 0321543254, 0-321-54325-4, 9780321543257
Where can I find a book's ISBN? ISBN codes are usually listed on a book's back cover, bar code, or copyright page.
What does an ISBN identify? Each edition of a book has its own separate ISBN. For example, each of the following would be considered a separate edition, even if they have the identical content: hardcover, softcover, large print, ebook, etc.
Why use ISBN? If an instructor recommends that students buy a very specific edition of a book, then it's best to search by ISBN. If the edition doesn't matter, it's best to search by title and author, so you can see prices for all editions.
