The National Library of Medicine adopted the 2012 MeSH for cataloging. Therefore MeSH heading in LocatorPlus have been changed to reflect the new 2012 vocabulary.
NLM will publish an article soon “What’s New for 2012 MeSH and MEDLINE Data Changes for 2012” (will provide link as soon as NLM provides it). However the Technical Bulletin did mention a few of the changes.
Medical Technology vs. Biomedical Technology: The specialty term Technology, Medical changed to Medical Laboratory Science so that it was less ambiguous. “In examining the cataloging records assigned the heading Technology, Medical, we determined that it was better to change the MeSH heading to Biomedical Technology, rather than Medical Laboratory Science because, in the majority of the cases, this is the heading that better reflects the topic of these works. About 400 records where Medical Laboratory Science is more appropriate have been identified programmatically and will be changed after YEP.”
Publications Types: Addresses can now be used for PT.
New MeSH descriptors: “Cataloging does not use MeSH terms that represent corporate names or uniform titles that reside in the national authority file. Therefore, HapMap Project has the annotation: CATALOG: use NAF entry. Catalogers should use the NAF heading: International HapMap Project.”
