Produced by the U.S. National Library of Medicine (NLM), Ovid MEDLINE covers the international literature on biomedicine, including the allied health fields and the biological and physical sciences, humanities, and information science as they relate to medicine and health care. Information is indexed from over 5,000 journals published world-wide.

Ovid OLDMEDLINE covers the international biomedical journals covering the fields of medicine, preclinical sciences, and allied health sciences. The citations were originally printed in hard copy indexes published from 1946 through 1965.

Also included is the In-Process & Other Non-Indexed Citations database which consists of In-Process and PubMed-not-MEDLINE records from NLM. The In-Process records are records that will be put into the Medline database after they have been enhanced with MeSH headings. PubMed-not-MEDLINE records are records from journals found in PubMed but not selected for MEDLINE.
