Are you wondering which textbook will be used in your class? Wondering if you have the most current version? We get it, why purchase another textbook when the one you have is just fine.

Locate the AHA product number (20-xxxx) on the back/bottom area of your existing textbook and see if it matches the AHA product number we show below. Chances are your existing textbook is still good, and if not, ask around because someone you know will loan you one.
