2012 Medical Subject Headings (MeSH) Now Available

The Introduction to MeSH 2012 is now available, including information on its use and structure, as well as recent updates and availability of data.

The default year in the MeSH Browser remains 2011 MeSH for now, but the alternate link provides access to 2012 MeSH. The MeSH Section will continue to provide access via the MeSH Browser for two years of the vocabulary: the current year and an alternate year. Sometime in November or December, the default year will change to 2012 MeSH and the alternate link will provide access to the 2011 MeSH.

Download 2012 MeSH in XML and ASCII formats. Also available for 2012 from the same MeSH download page are:

  • Pharmacologic Actions (Forthcoming)
  • New Headings with Scope Notes
  • MeSH Replaced Headings
  • MeSH MN (tree number) changes
  • 2012 MeSH in MARC format
