Indexing principles for Category G - Biological Sciences

Category G1 & G2 Indexing

Category G1 contains mainly the MeSH headings for the disciplines in the biological sciences such as:

  • BIOCHEMISTRY
  • BIOLOGY
  • NEUROSCIENCES

Category G2 contains mainly the MeSH headings for the various health occupations such as:

  • MEDICINE
  • DENTISTRY
  • OPTOMETRY

Several of the MeSH headings in these categories exist also as subheadings (see Indexing Manual 19.7+). The MeSH headings are used for general aspects of the field while the subheadings are used with specific anatomical terms, diseases, organisms, biological processes, and drugs. The indexer will use the subheadings much more frequently than the “duplicate” MeSH heading.

Category G MeSH Heading Subheading
ANATOMY /anatomy and histology
PHYSIOLOGY /physiology
PHARMACOLOGY /pharmacology
