<p> Harrison's Principles of Internal Medicine: PreTest Self- Assessment and Review has been designed to provide phy-sicians with a comprehensive, relevant, and convenient instrument for self-evaluation and review within the broad area of internal medicine. Although it should be particularly help ful for residents preparing for the American Board of Internal Medicine (ABIM) certification examination and for board-certified internists preparing for recertification, it should also be useful for internists, family practitioners, and other practicing physicians who are simply interested in maintaining a high level of competence in internal medicine. Study of this self-assessment and review book should help to (1) identify areas of relative weakness; (2) confirm areas of expertise; (3) assess knowledge of the sciences fundamental to internal medicine; (4) assess clinical judgment and problem-solving skills; and (5) introduce recent developments in general internal medicine. </p>
