The MeSH Database

The MeSH Database available from PubMed's home page and database selection menu allows you to:

  • locate and select MeSH terms (Headings, Subheadings, Supplementary Concept Records, and Publication Types) for use in PubMed searches
  • see the definition and other helpful information for a MeSH term
  • see the position of MeSH terms in the hierarchy
  • select MeSH heading/subheading combinations to build a PubMed search

An example of a full MeSH Database record (see text version):

Note: Searching with MeSH subject terms excludes citations from MEDLINE journals that have not yet been fully indexed, as well as other PubMed citations that are not indexed for MEDLINE (e.g., citations that are out of scope for MEDLINE, such as a volcanology article in Science). These records do not (or do not yet) include MeSH subject terms.
