The U.S. National Library of Medicine has created an educational video to help people understand and use the MeSH vocabulary in searching Medline and PubMed.
Branching Out: The MeSH® Vocabulary describes the structure and content of the Medical Subject Heading thesaurus, shows how indexers use it to index documents, and instructs searchers on how to utilize it to find documents and understand the topic.
This is an excellent introduction to the nature of controlled vocabulary and its value in enabling information retrieval.
