Wikipedia, as most are aware, is the free online encyclopedia that covers nearly everything. Almost anyone can edit it, and nearly everybody reads it. As of June 2011, it had over 3.6 million articles in the English language of which approximately 23,000 pertained to the practice of medicine, and 6,700 discussed aspects of pharmacology. The medical pages in a given month receive between 150 and 200 million page views1 while the pharmacology content receives approximately 35 million. 2 For the entire encyclopedia, 40,000 people make more than five edits each month, 3 though a much smaller number of editors are actively involved with medicine. However, users involved with WikiProject Medicine are a dedicated group of volunteer physicians, students, and non-professionals with the goal of providing people with free access to reliable, understandable, and current health information. 4
