Established in 1927 by the American College of Physicians (ACP), the Annals of Internal Medicine is the leading journal for studies in internal medicine. The purpose of the journalñto promote excellence in the clinical practice of internal medicineñis supported by presentation of a wide variety of experimental and clinical subject matter in the Article, Brief Communication, Update, and Review formats. And to support the belief that physicians should also be well-informed citizens of both the medical community and society at large, Annals offers background and discussion of issues that influence both physicians and patients. This information is primarily carried in the Perspective, In the Balance, and Editorial formats. In addition, the journal presents personal narratives in the On Being a Doctor and the On Being a Patient formats that convey the feeling and the art of medicine.

ACP Journal Club summarizes the best new evidence for internal medicine from over 120 clinical journals. Once a bimonthly stand-alone journal, ACP Journal Club is a monthly feature of Annals of Internal Medicine. Research staff and clinical editors rigorously assess the scientific merit of the medical literature as it is published and a worldwide panel of over 5000 physicians assesses the clinical relevance and newsworthiness of rigorous studies.
