Stedman's Medical Dictionary, 28th Edition, has been thoroughly reviewed and updated by consultants from all the major medical and health science specialities. New consultants were added to this edition covering the specialities of Endocrinology, Gastroenterology, Geriatrics, and Rheumatology. Enhancements such as these make this dictionary the most reliable, must-have resource available for healthcare.
I can't say I have read every word, but I referenced it many a time over the years. It also made a good footrest while I was transcribing for physicians.
