Subject and Name Authority Resources

To create consistent subject headings and names in bibliographic records, we use controlled thesaurus and authorized headings.  For subject headings, we use the Library of Congress Subject Headings. For names of persons, places or institutions, we use a variety of online resources, based on the Library of Congress Authority File.
