MeSH Coming Attractions

[corrected 1999/01/11]

[published erratum appears in the NLM Technical Bulletin. 1998 Nov-Dec;(305):e1]

[corrected 1999/08/10]

[published erratum appears in the NLM Technical Bulletin. 1999 Jul-Aug;(309):e1]



There were 303 [corrected 1999/01/11] descriptors added to the 1999 MeSH including 38 Publication Types. Five descriptors were deleted. A list of new Publication Types appears at the end of this article with their scope notes.

Changes to the following four categories are highlighted as of particular interest and are described in more detail later in this article:

  1. Fungi
    Many new headings were added to the B5 tree and others modified to reflect developments in the taxonomy of the fungi.

  2. Genetics
    New headings were added to the G5 tree and to the E5 tree (Techniques).

  3. Delivery of Healthcare
    New headings were added to reflect recent Federal legislation and other developments.

  4. Chemicals and Drugs
    A listing of all 71 new D category headings appears elsewhere in this issue. A new Subcategory D27 was created to group all MeSH Headings used as Pharmacologic Actions. A sample of this new Subcategory is shown later in this article under Chemical Actions and Uses (D27).

As always, comments and suggestions regarding possible new headings and changes to existing headings are welcome. Comments and suggestions may be made from the MeSH Home Page at: http://www.nlm.nih.gov/mesh/meshsugg.html.

Fungi (B5)

The Fungi tree was enhanced with 23 new MeSH headings to reflect developments in taxonomy. There are also many MeSH Heading (MH) changes and Tree changes as fungi names and taxonomies have undergone alterations.

Many fungi have a sexual (teleomorphic) and asexual (anamorphic or mitosporic) form. These are also called perfect and imperfect states. Each form (state) has its own taxonomic name.

Reciprocal cross references (see related notes) have been made between each related teleomorph and anamorph (mitosporic) fungus. For example, under the MeSH heading Colletrotrichum in the printed Annotated MeSH there will be the notation: see related Phyllacorales. And under Phyllacoralles there will be the notation: see related Colletrotrichum.

Chemical Actions and Uses (D27)

This new subcategory was created to logically arrange the Pharmacological Action headings within the MeSH hierarchy. A full listing of the Pharmacological Action headings is available at the front of the printed Tree Structures. Except for three new headings (Chemical Actions, Chemical Actions and Uses, and Uses of Chemicals and Drugs) the headings in this new subcategory were previously found elsewhere in Category D. These headings also appear elsewhere, as in past years, but here all appear together, regardless of particular organ system or mode of action. Note that individual substances are not included in D27.

A partial example of the new subcategory is shown here and this example includes headings that also appear in D8 and D14.

Publication Types

In coordination with planned changes in NLM cataloging practice and the implementation of the Integrated Library System (ILS), 38 new Publication Types were created and modifications were made to some existing Publication Types (PTs). None of these new PTs will be used for indexing journal articles; these PTs will be used exclusively for the cataloging of books and other materials.

Previous NLM cataloging practice used form subheadings to characterize the genre or format of presentation of information as in /bibliographies or /union lists. With the new ILS, such form subdivisions or subheadings will be replaced with PTs. As a result, there was a need for new PTs to reflect the breadth of materials in the NLM collections.

Changed Publication Types

Changes were made to three Publication Types used to index journal articles in order to allow parallel bibliographic control of materials indexed (e.g., journal articles) and of those cataloged (e.g., books). Previously, for example, cataloging and indexing used similar but not identical terms for materials consisting of the discussion or presentation of legal cases. Now the same PT, Legal Cases, will be used for similar information, presented in a similar manner whether this material appears in a book or a journal article. This will simplify retrieval of information, providing more complete searches against multiple interfaces. The three changed PTs are:

Abstract was changed to Meeting Abstracts [corrected 1999/08/10]
(this PT is used for abstracts of presentations at various types of meetings, not for designating abstracts accompanying journal articles; it is currently used in AIDSLINE, HealthSTAR, HISTLINE, POPLINE, SPACELINE, and TOXLINE)

Legal Brief was changed to Legal Cases

Meeting Report was changed to Congresses
