Boehr D, Willis S. Cataloging News — 2016. NLM Tech Bull. 2016 Nov-Dec;(407):e6.
The National Library of Medicine (NLM) adopted the 2016 MeSH vocabulary for cataloging on November 23, 2015.
Accordingly, MeSH subject headings in LocatorPlus were changed to reflect the 2016 MeSH vocabulary and appear in that form as of November 23, 2015.
When year-end processing (YEP) activities are completed in mid-December, the NLM Catalog, MeSH database, and translation tables will be updated to reflect 2016 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 2016 MeSH changes until Spring 2016.
In general, the Cataloging Section implemented the vocabulary changes in NLM bibliographic records for books, serials, and other materials, as they were applied for citations in MEDLINE. Below are a few highlights:
In order to improve indexing and cataloging consistency and efficiency and to make database searching easier and more straightforward, the subheading /diagnostic use was deleted from MeSH.
Cataloging and Indexing Policy:
To cover the concept of Diagnostic Use related to diseases:
To cover the concept of Diagnostic Use related to clinical and physiological conditions:
To cover the general concept of the diagnostic use of substances:
Use instructions for catalogers or indexers found in the MeSH Annotation field were standardized to simplify, clarify, and make the annotations more useful to the cataloger or indexer.

New descriptors were created for Human only or Mouse only embryonic stem cells. Catalogers should use Embryonic Stem Cells if no specific type is specified.
Catalogers should be aware of the numerous additions and changes that were made to the F3 tree to reflect the significant changes in The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Below are some examples:
Disruptive, Impulse Control, and Conduct Disorders
Feeding and Eating Disorders
Sleep Wake Disorders
MeSH terms for Food in the J02 tree were placed under the new term Diet, Food and Nutrition in G07. The original treeing in J02 was also retained. MeSH terms for specific fruits and vegetables are now treed only in B tree– Plants. Catalogers should coordinate specific fruit or vegetables with Fruit or Vegetables as appropriate.
The word biogenesis, as it appears in the literature, has multiple meanings. For 2016, the MeSH term Biogenesis (Entry Term: Origin of Life) was replaced by the heading – Organelle Biogenesis and a new heading Origin of Life was created. During YEP, the Cataloging and Metadata Management Section (CaMMS) mapped bibliographic records with Biogenesis to Origin of Life since the majority of the material in our database was on this topic. During post-YEP processing, for a small number of selected records, Organelle Biogenesis will either replace Origin of Life or be added to the bibliographic record.
Prior to 2016, specific wars and conflicts were treed only in the K Tree – History under the appropriate time period. With 2016 MeSH, terms for specific wars and terms for warfare were grouped together under the new term Warfare and Armed Conflicts in the I Tree. Treeing of specific wars in the K Tree – History was retained. Catalogers do not have to coordinate the relevant history time period with the specific names war or conflict.

A summary of the DTD and XML changes for the NLMCatalogRecordSet DTD and CatfilePlus and Serfile XML for 2016 is available, see DTD AND XML CHANGES FOR THE NLM 2016 PRODUCTION YEAR.
In June 2015, NLM proposed discontinuing distribution of its bibliographic records with artificially reconstructed subject strings in CATLINE and SERLINE products. This proposal was sent to the Regional Medical Libraries, MEDLIB, and MEDCAT discussion lists, as well as to subscribers of the NLM MARC21 files. Responses to the proposal were unanimously in favor of discontinuing the distribution of subject strings and having the records in the distributed files match the records as they appear in LocatorPlus and the NLM Catalog.
Therefore, NLM is pleased to announce that beginning with the December 2015 distribution of new records in CATFILE and SERFILE, NLM subject terms will be distributed with topical subjects recorded in 650 $a or 650 $a $x; geographic subjects recorded in 651 $a or 651 $a $x; and publication type/genre terms record in 655 $a. In January 2016, the entire CATFILE and SERFILE databases will be released with these updates made to all the records. NLM recommends that libraries that want their data to be consistent with the NLM files download the full update.
Catalogers in other libraries that use MeSH are encouraged to follow NLM practice in assigning their subjects. Under no circumstances should a library edit a record in OCLC to re-create a string and remove the 651 and 655 fields. Any desired editing should be done only in your local catalog. After January 2016, libraries will be required to establish medical subjects in a deconstructed format in OCLC. OCLC will be updating all records with 650 fields with a second indicator of 2 to follow the new NLM practice. NLM is working with authority vendors to provide guidance on how local catalogs can be updated.

The 2016 annual MeSH/MARC file will include the NLM Classification 060 field in selective MeSH records, populated with data provided by CaMMS. However, the classification number will not appear in the MeSH browser until 2017.
