MeSH 2016 — Implications for LocatorPlus, NLM Catalog, and the NLM Classification

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.

A. MeSH 2016 Changes in NLM Bibliographic Records and Cataloging Policy

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:

1. Deletion of Qualifier: diagnostic use

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:

• Use the diseases with the subheading /diagnosis (or specific one treed under it)
• Use specific diagnostic technique
• Use specific chemical(s) or physical agent(s) with no subheadings

To cover the concept of Diagnostic Use related to clinical and physiological conditions:

• Use the organ or process terms with appropriate subheadings
• Use the specific diagnostic technique
• Use the specific chemical(s) or physical agent(s) with no subheadings

To cover the general concept of the diagnostic use of substances:

• Use MeSH heading Diagnostic Uses of Chemicals

2. Standardized Wording of MeSH Annotation Instructions

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.

Old Phrase in MeSH Annotation	New Phrase in MeSH Annotation
CATALOG: coordinate with specific NAF entry if applicable	CATALOGER: coordinate with specific NAF entry if applicable
CATALOG: Do not use	CATALOGER: Do not use
CATALOG: Do not use for current materials	CATALOGER: Use for historical material only
CATALOG: do not use: for indexers only	CATALOGER: Do not use

3. Embryonic Stem Cells

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.

Embryonic Stem Cells [A11.872.700.250]

Human Embryonic Stem Cells [A11.872.700.250.750]

Mouse Embryonic Stem Cells [A11.872.700.250.875]

4. Mental Disorders

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:

New Mental Disorders

Autism Spectrum Disorder

Bipolar and Related Disorders

Childhood-Onset Fluency Disorder

Gender Dysphoria

Hoarding Disorder

Motor Disorders

Neurodevelopmental Disorders

Psychological Trauma

Social Communication Disorder

Specific Learning Disorder

Speech Sound Disorder

Trauma and Stressor Related Disorders

Changed Mental Disorders 2015 Impulse Control Disorders Eating Disorders Delirium, Dementia, Amnestic, Cognitive Disorders Paraphilias Sleep Disorders

2016 Disruptive, Impulse Control, and Conduct Disorders Feeding and Eating Disorders Neurocognitive Disorders Paraphilic Disorders Sleep Wake Disorders

In addition to the above, several descriptors were retreed. One descriptor was deleted: Mental Disorders Diagnosed in Childhood is now an Entry Term to Neurodevelopmental Disorders.

5. Diet, Food, and Nutrition

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.

6. Origin of Life vs. Organelle Biogenesis

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.

7. Wars and Warfare

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.

8. Publication Types (PTs) and Related Terms:

Clinical Study - Catalogers are likely to have little use for this PT. Prefer the new topical term, Clinical Studies as Topic.

Graphic Novels - This was formerly an Entry Term to Cartoons. The new PT is treed under Pictorial Works. There is not yet a corresponding "As Topic" term.

Blogs - Catalogers will use this new PT when cataloging a blog. Blogging is used when the item discusses a blog.

Public Service Announcements - Catalogers will use this new PT when cataloging a public service announcement. Public Service Announcements as Topic is used when the item discusses public service announcements.

Newspaper Terms - NLM catalogers will not use the PT Newspaper Article for current materials or for reprints of newspaper articles. The corresponding topical term is Newspapers as Topic (formerly Newspapers). Newspapers is now an Entry Term to the PT Periodicals.

9. MeSH Descriptors Not Used by Catalogers:

Umbrella Terms - Catalogers should use the specific MeSH treed below these terms.

Diet, Food, and Nutrition

Pharmacological and Toxicological Phenomena and Processes

Warfare and Armed Conflicts

NAF Terms - Catalogers should use the Name Authority File record.

African Union

Annotation: CATALOGER: use NAF entry

Catalogers should use LCCN no2001048790 in the 610 field of the bibliographic record. Coordinate with 650 X2 Organizations.

Children's Health Insurance Program

Annotation: CATALOGER: use NAF entry

Catalogers should use LCCN no2009106489 in the 610 field of the bibliographic record. Coordinate with 650 X2 State Health Plans if applicable.

B. Additional Database Changes

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.

C. Change to Subject Headings in Distributed NLM CATLINE and SERLINE Products

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.

D. Changes to MeSH/MARC File

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.
