We are very comprehensive in many areas within these disciplines. Most if not all participants have extensive experience as academic library selectors or bibliographers.
Subjects primarily come from controlled languages.
Note though that many of these are employed primarily as key words and only occasionally as subjects. The purpose of this list of disciplines, garnered from several UC campus catalogs, would be to provide perhaps more familiar terms for users to search on and to provide a framework for applying meta-subject terms. These are terms that researchers have traditionally used to describe their departments and programs. They function as subject terms at a very broad level and thus as meta-subject terms. Key Words are meant to supplement, in every possible way, within reason, the subject terms.
