What is Medline

Medline is an online database of biomedical journal citations created by U.S. National Library of Medicine.  Approximately 5400 journals published in the US and more than 80 other countries are currently indexed. (CINAHL currently includes approx 700 journals). MEDLINE records are indexed with NLM's controlled vocabulary, the Medical Subject Headings (MESH). There is some overlap with CINAHL but each has its own unique content.

UVic Libraries has MEDLINE from two different providers - Ebscohost and OVID.
