MeSH Search

MeSH (Medical Subject Headings) is the U.S. National Library of Medicine's controlled vocabulary.

  • It is used for indexing articles for MEDLINE/PubMed.
  • MeSH terminology provides a consistent way to retrieve information that may use different terminology for the same concepts.
  • It pulls together all articles on a concept including synonyms (myocardial infarction/heart attack) and allows for spelling variations (estrogen/oestrogen).

Access MeSH in PubMed from the drop-down menu OR click on MeSH Database from the PubMed homepage.

Enter a topic into the Search bar and click the Search button. The MeSH database offers options to clarify and focus searches.

Click the selected MeSH term to view the definition, often with the year introduced, the entry terms with the subheadings, related and linked terms, also MeSH hierarchy of linked terms.
