Guidelines for applying content designators:

The content designators identify the subelements occurring in a name or name/title heading that contains a personal name constructed according to the generally accepted cataloging and thesaurus-building rules [e.g., Anglo-American Cataloguing Rules (AACR 2), Library of Congress Subject Headings (LCSH)].

Personal names used in phrase subject headings (e.g., John, the Baptist, Saint, in the Koran) are contained in the X50 fields.

The indicators, subfield codes, and input conventions for the personal name fields 100, 400, 500, and 700 follow similar patterns. Guidelines for applying them are below. Subfields are grouped by type of entry.

For indicator and subfield code definitions and examples, National level (NLR) record requirements, and designator repeatability, see table below. An asterisk ( * ) in the column indicates that the requirement varies. See table in the specific field.:
