The 1XX field in a node label or facet indicator record contains an unestablished term (usually a fairly broad one) that may be used in the systematic section of a thesaurus to indicate the logical basis on which a category has been divided.  The term in the 1XX is not used as an indexing term or subject heading.  This example has code r in 008/11 indicating it came from the Art and Architecture Thesaurus.  Reference (4XX and 5XX) fields are not used in a node label record.
