The National Library of Medicine (NLM) was established in 1836 as the library of the Army Surgeon General's Office. It was transferred to the Department of Health, Education, and Welfare and became known as NLM in 1956. In support of its mission to collect, preserve, and disseminate biomedical information, NLM has assembled the largest collection of biomedical literature in the world. Included are over 8 million books, journals, technical reports, and other print and audiovisual materials, as well as the nation's largest medical history collection. Services of NLM include computer-based literature retrieval services, interlibrary loan services, programs and grant support for medical libraries, toxicology information services and biotechnology information services. Eight major libraries around the country, the National Network of Libraries of Medicine (NN/LM) coordinate online reference retrieval and interlibrary loan services for libraries in their region. DATABASES: Free access to MEDLINE, MEDLINEplus (Consumer health information), and other NLM databases are available to those with World Wide Web access at: Fact sheets and pocket guides describing the databases are available. A MEDLARS management service desk at NLM is staffed to answer questions about the online system.
