This document describes the key components and functions of a subject authority file used for indexing documents. It consists of controlled vocabulary terms structured in a hierarchical manner to express concepts. The subject authority file contains mechanisms like scope notes, hierarchical and associative relationships between terms, and synonyms to enable consistent indexing of documents according to their conceptual coverage. Indexers can only assign terms that appear in the approved subject authority list to ensure concept indexing is used.
