What are Medical Subject Headings aka MeSH?

The Medical Subject Headings make up the controlled vocabulary of the National Library of Medicine (NLM). It is used for indexing articles, for cataloging books and other holdings, and for searching MeSH-indexed databases, including MEDLINE and CINAHL with Full Text.

The Medical Subject Heading (MeSH) terminology provides a consistent way to retrieve information that may use different terminology for the same concepts. MeSH organizes its descriptors in a hierarchical structure so that broad searches will find articles indexed more narrowly.

For more detailed information concerning MeSH see the Medical Subject Headings or the Introduction to MeSH (from the U.S. National Library of Medicine)
