'''''PFAN optional practice:'''''

''PFAN optional practice:''For a geographic name heading that may also be used as a geographic subdivision, determine the form in which the heading is to be used as a geographic subdivision following the guidelines in instruction sheet [https://www.loc.gov/aba/publications/FreeSHM/H0830.pdf H 830 of the ''Subject Headings Manual'']. Enter the text of the geographic subdivision form in a 781 field with second indicator 0. For a geographic heading that is used directly, such as a country, enter the data in a single $z subfield. For a geographic heading that is used indirectly through a larger geographic entity, such as a city, enter the data in two successive $z subfields. Use no other subfields. Make no changes to values in bytes of the 008.

Follow these guidelines for newly-created authority records. Add a 781 field to an existing record when making any other change to it. If revising an existing record that contains a 667 field subject cataloging usage note indicating the proper geographic subdivision form, delete the 667 field and replace it with a 781 field.
