Other Changes to the Schedule

Class number captions were also revised in other schedules. For example:

Instructional notes were added or modified to clarify classification practices as needed, e.g., a note was modified at WZ 290 to clarify the types of works to be classified there.

Changes to the Index

Seventy-one new index entries were created of which forty-one are from the 2008 MeSH; the remainder are MeSH terms from previous years. Numerous main index entries and cross references were modified to reflect changes in the MeSH vocabulary. In particular, some major categories of index terms affected by MeSH changes were:

Publication types, e.g.,

          Biography [Publication Type] to Biography

Topical terms that duplicate publication types, e.g.,

          Biography changed to Biography as Topic

All index entries pertaining to the aforementioned schedule additions and changes were modified.
