• The Abstract display will be modified to accommodate changes to Supplementary Concept Records in the MeSH® vocabulary (see below).

PubMed Abstract Display Modified for Supplementary Concepts

The MeSH Vocabulary includes nearly 200,000 records known as the Supplementary Concept Records (SCRs). Until recently these were primarily records for drugs and substances plus a small percentage of protocols. Beginning with 2011 MeSH, SCR records will also include disease terms that are not MeSH headings as explained in the forthcoming article, What's New for 2011 MeSH®. [Editor's Note: This article was published on December 10, 2010.]

PubMed will display SCR terms in the expandable section for supplemental information of the Abstract format as follows:

• Chemicals and substances will continue to display under the header, Substances.
• Protocols and disease terms will display under the new header, Supplementary Concepts.

All SCRs will display on the MEDLINE format with the RN field tag.

All SCRs can be searched using these search tags:

[supplementary concept]

[substance name]

[nm]

Example: kindler syndrome [nm]
