Database Description

MEDLINE®

Content
MEDLINE (MEDLARS® onLINE), produced by the U.S. National Library of Medicine (NLM), is one of the major sources for biomedical literature. MEDLINE corresponds to three print indexes: Index Medicus™, Index to Dental Literature, and International Nursing Index. Additional materials not published in Index Medicus are included in the MEDLINE database in the areas of communication disorders, and population and reproductive biology. MEDLINE is indexed using NLM's controlled vocabulary, MeSH® (Medical Subject Headings).

Abstracts, which are taken directly from the published articles, are included for over 59% of the records added from 1975 forward. Records added before 1975 do not contain abstracts; records added from 1985 to the present have abstracts for about 69% of the records. Approximately 400,000 records are added per year, of which more than 85% are in English.

Sources
MEDLINE includes indexing to articles from 3,700 journals published in more than 70 countries. Citations to chapters or articles from selected monographs were also included from May 1976 through 1981.
