The 800 articles in this encyclopedia, written by medical personnel in a variety of fields, set it apart from recent titles, such as DK's New Medicine, which tend to be one-volume works and have far fewer entries. The format is similar to that used in Gale's other medical encyclopedias (e.g., Encyclopedia of Genetic Disorders; Encyclopedia of Mental Disorders), with most of the signed articles running two to three pages. Entries for diseases include a definition, description, causes and symptoms, diagnosis, treatments and expected results, prevention, a list of resources, and key terms in sidebars. High-quality photos and illustrations are scattered throughout, and the layout is attractive and easy on the eyes, with color used judiciously to highlight and separate sections. Each volume includes a list of entries for the complete set, and Volume 4 includes a list of medical and alternative medicine organizations, an extensive glossary, and a general index. A spot-check indicates that most entries have had at least some updating since the second edition. BOTTOM LINE With text aimed at a general adult audience and avoiding medical jargon when possible, this is highly recommended for public libraries and academic libraries serving lower division undergraduates.—Rosanne M.
