1. MeSH (Medical Subject Headings) is the National Library of Medicine's controlled vocabulary thesaurus used for indexing articles in MEDLINE/PubMed. 2. MeSH contains descriptors that are arranged hierarchically and alphabetically, along with publication types, qualifiers, and supplementary concept records. 3. MeSH has been continually expanded and updated since the 1960s to improve coverage and allow for deeper indexing of the growing body of medical literature.
