Medical Subject Headings
What's New in MeSH
The MeSH Browser has been updated and is now Section 508 compliant .
John Kilbourne, MD has been selected as the Head of the Medical Subject Headings Section.
Due to the ever increasing number of concepts and terms in MeSH, it is necessary to increase the number of unique identifiers available for the MeSH vocabulary. Thus, the length of the unique identifier for elements such as Descriptors and Supplementary Concept Records will expand from 7 to 10 characters. 8-character unique identifiers will expand to 10 characters. These changes will begin for unique identifiers created beginning April 15, 2013. The format of existing unique identifiers will not be changed.
