eSH® 2010 - Implications for LocatorPlus® , NLM® Catalog, and the NLM Classification

The National Library of Medicine® (NLM) adopted the 2010 MeSH® vocabulary for cataloging beginning on November 9, 2009.

Accordingly, MeSH subject headings in LocatorPlus were changed to reflect the 2010 MeSH vocabulary and appear in that form as of November 9, 2009.

When year-end processing (YEP) activities are completed in mid-December, the NLM Catalog, MeSH database, and translation tables will be updated to reflect 2010 MeSH.  Until then, note that there will be a hiatus in the addition of new and edited bibliographic records to the NLM Catalog.

The Index to the NLM Classification will not reflect 2010 MeSH changes until Spring 2010.

MeSH 2010 Changes in NLM Bibliographic Records

In general, the Cataloging Section implemented the vocabulary changes in NLM bibliographic records for books, serials, and other materials, as they are to be applied for citations in MEDLINE®. For highlights about 2010 MeSH, see the upcoming articles What's New for 2010 MeSH and MEDLINE Data Changes — 2010.

Publication Types (PTs):
Of the four new publication types, Cataloging will use Webcasts for current material. During YEP, the PT Webcasts was retrospectively added to Center for Information Technology (CIT) videocast records of special NIH events, seminars, and lectures for current materials. Incunabula and Postcards will be used by Cataloging for historical materials only.

Other New Terms not used by Catalogers for Current Materials:
  • American Recovery and Reinvestment Act [Catalogers will use the heading United States. American Recovery and Reinvestment Act of 2009 from Name Authority File (NAF)]
  • Health Level Seven [Catalogers will use the NAF heading Health Level Seven (Organization)]
  • Organism Forms [Catalogers will use specific terms treed under this broad term, such as Spores]

Additional Database Changes

Linking ISSN (MARC 022 $l)
The ISSN International Center has assigned a new linking ISSN (also called ISSN-L) for every serial in the Center's ISSN database. The ISSN-L matches one of the existing ISSNs, and serves to link multiple media versions of the same title. During YEP, the ISSN-Ls that matched the ISSNs of existing serial titles in LocatorPlus were loaded into 022 $l ("l" is letter L in lower case), a new subfield in the bibliographic records designated for this purpose. After YEP, the linking ISSN will be added manually to new serial records.

Language Codes Updated (MARC 008 Position 35-37 and MARC 041)
Three languages were revised to reflect changes in the MARC Code List for Languages:
  • Serbian, previously coded as scc, is now coded srp.
  • Croatian, previously coded as scr, is now coded as hrv.
  • Moldovan, previously coded as mol, is now coded as rum.

Resource Description and Access (RDA)
Three new fields (336 - Content Type; 337 - Media Type; 338 - Carrier Type) and several code values for the 007 and 008 were added to the data structure to accommodate the forthcoming new cataloging rules, RDA. NLM is coordinating the testing of RDA along with the Library of Congress (LC) and National Agricultural Library (NAL).
