Category K - Humanities

Indexing Principles

Category K contains the MeSH terms in the area of the humanities. It includes terms for:

  • art
  • literature
  • philosophy
  • ethics
  • history

Terms in this category tend to be indexed as IM concepts.

The subheadings available to Category K terms are listed below:

  • /classification
  • /education
  • /ethics
  • /history
  • /psychology
  • /statistics & numerical data
  • /trends

This list is quite limited and, for many terms in Category K, either no subheadings are permitted or only one or two are permitted. Therefore, Category K terms are frequently indexed with no subheading.
