The Medical Subject Headings (MeSH) is a hierarchically-organized controlled vocabulary developed and maintained by the National Library of Medicine (NLM). MeSH serves as the authoritative thesaurus for indexing, cataloging, and searching biomedical and health-related information across multiple NLM databases, most notably MEDLINE/PubMed.
MeSH provides a consistent way to retrieve information that may use different terminology for the same concepts. It consists of descriptors arranged in a hierarchical structure that permits searching at various levels of specificity. The vocabulary is updated annually, with new descriptors added and existing ones modified to reflect advances in medical knowledge.
MeSH is primarily used for:
MeSH data is available in multiple formats to support different use cases:
The vocabulary is accessible through various interfaces including the MeSH Browser, programmatic APIs, and downloadable data files. Updates are provided annually for the main vocabulary, with daily updates for supplemental concept records.
