eMedicine is an online clinical medical knowledge base that was founded in 1996 by Scott Plantz and Richard Lavely, two medical doctors. The website is searchable by keyword and consists of approximately 6,800 articles, each of which is associated with one of 62 clinical subspecialty textbooks. Pediatrics, for example, consists of 14 subspecialty textbooks (endocrinology, genetics, cardiology, pulmonology, etc.). For example, 750 articles comprise the textbook on emergency medicine. Each article is authored by board certified specialists in the subspecialty to which the article belongs. The article's authors are identified with their current faculty appointments. Each article is updated yearly and the date is published on the article.
