'''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 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.

Do not add a 781 field to a record for a geographic name heading that is not appropriate for use as a subject added entry (008/15 value Ab@), such as the earlier name of a jurisdiction that has undergone a linear name change, for example, Ceylon.
 +
 +
Do not add a 781 field to a NAR for a place name that is not appropriate for use as a geographic subdivision, such as a city section, for example, North End (Boston, Mass.)
 +
 +
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.
