eMedicine is a medical information site developed over the past four years by more than 10,000 physician authors and editors from nearly 1,000 academic medical institutions. The aim is to make available, free and online, more than 50 medical subspecialty texts that can be updated as soon as new research information becomes available. Each topic is peer reviewed by four physicians and a doctor of pharmacy, whose names are listed. At this time, the site offers an 8,000-page searchable textbook on emergency medicine. A separate and extensive series of pediatric subspecialty textbooks is planned, as is a consumer text covering diagnosis and treatment of 500 of the most common diseases.
