1960

In 1960 the National Library of Medicine introduced Medical Subject Headings (MeSH), a comprehensive controlled vocabulary for the purpose of indexing journal articles and books in the life sciences. MeSH serves as a thesaurus that facilitates searching; it is used by the MEDLINE/PubMed article database and by NLM's catalog of book holdings.
