Notes Accordingly, the glossary is itself a controlled vocabulary, more specifically a thesaurus. So you
will find all of the standard features of any thesaurus: broader, narrower, and variant term indicators,
as well as scope notes. In this case, however, the scope notes provide the definition of the particular
glossary term being presented.
