If you are ordering a new textbook, you can find out exactly what you’re getting by looking at the ISBN (International Standard Book Number). ISBNs identify not just unique books, but unique complete packages. In other words, the ISBN for a textbook by itself is not the same as the ISBN for a textbook that comes with an access code, workbook, or other supplement.

If you are ordering a used textbook, the book may or may not include the supplements. Be sure to check the comments on the copy you are ordering (and not just the title) to find out if the textbook you are ordering is missing the supplements you need. For the used textbooks we are selling, click “(view details)” on the product page to see comments on specific copies.
