Policy and formulation

  • Refer to local constant data (in the Shared Authorities file in Connexion) for frequently-used terms.
  • Prefer AAT or LCSH; however, any controlled vocabulary is acceptable.


  • Restrict to actual fields of endeavor; don't apply to literary or artistic movements.
  • Use broader terms in the 372 field, and specific terms in the 374 field.

  • Use Shakespeare as field of activity for all people who have anything to do with Shakespeare--which we know because we're cataloging it--even if it's only one thing and the person is completely obscure.
    • Other personal name headings may be used in 372, but apply these more conservatively than with Shakespeare.
  • Terms can indicate both practitioners and scholars/critics. For example, use Music for musicians and musicologists; Theater for actors and theater historians.
  • When establishing translators, include a subfield ‡a for the language they are translating a work from. (Include the language that a work has been translated into in the 377.)

Corporate bodies

  • Use broader terms in the 368 field, and specific terms in the 372 field.
