Newly Maintained MEDLINE for 2011 MeSH Now Available in PubMed
The 2011 PubMed system will be available in mid-December. Links to other articles pertinent to the new system are provided to the right.
There are a few changes to PubMed this year:
Changes to the Limits page were reported in the article, Comings and Goings for PubMed® Limits.
- Users of XML data may want to see additional information including DTD and XML changes for the NLM 2011 production year:
XML users can keep up to date by subscribing to an announcement mailing list at this site: http://www.ncbi.nlm.nih.gov/mailman/listinfo/utilities-announce.
- 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]
Example: kindler syndrome [nm]
[Note: The changes described above appeared in PubMed on December 13, 2010. At the same time the link to the Journals Database on the PubMed homepage was replaced with the link, Journals in NCBI Databases which connects to the NLM Catalog (see: NLM Catalog: New Search Features for Journals Cited in Entrez Databases.)]
