What are some books to learn medical terminology?

A standard college medical terminology textbook is "Medical Terminology for Health Professions," by Ann Ehrlich of Goddard College. This textbook has passed through several editions and can be obtained with a companion CD.

Another medical terminology book that attempts to make arcane terms accessible to a lay audience is "Exploring Medical Language," by Myrna and Danielle LaFleur Brooks. One of the selling points of this book is that, though it also includes a companion CD, it also comes with hard-copy flash cards, suggesting its intended purpose is as a college-level introductory text for both general and health-related subject majors who expect to be tested.
