JournalDoc is a medical information service designed specifically for doctors, health care professionals, and their patients. In order to provide you with highly relevant article citations, experts in each of the medical specialties pre-screen articles and determine their suitability for your specialty. The Search Indexes are also specialized. So that you may quickly find relevant articles in our customized databases. We are not a Search Engine that crawls through cyberspace, and retrieves thousands of articles, many of which are irrelevant. The development of the JournalDoc Search Indexes was supported by Grants # --------- and # __________ from the National Library of Medicine, the National Institutes of Health, and the FDA. The Key Ar6ticle Collections are based on Nelson Information Systems MKSAP Reprint Collections, which were developed in collaboration with the American College of Physicians. The principal investigator on the grants , and the founder of both NIS and JournalDoc is John M. Nelson, MD. Dr. Nelson is a board-certified internist, and a Fellow of the American College of Physicians, and the American College of Physician Executives
