UMLS Home Page
The 1998 version of UMLS contains 1,052,000 names for 476,000 concepts in more than 40 biomedical vocabularies, thesauri, and classifications. International by design, Meta-98 contains French, German, Spanish, Portuguese, and transliterated Russian translations of MeSH terms.

UMLS Knowledge Source Server
Requires registration.

NLM Sourcerer Project
Sourcerer, a Perl CGI interface, is a component of the UMLS Project. This site gives information on the UMLS semantic strategies and contrasts natural language processing with use of predefined vocabularies, giving examples of each. Also explains Sourcerer's programming strategy.

NLM Medical Subject Headings (MeSH)
MeSH is the National Library of Medicine's controlled vocabulary thesaurus. MeSH terms are carefully connected by "broader-than," narrower-than," and "related" links. These links show the relationship between related terms and provide a hierarchical structure that permits searching at various levels of specificity.
