Field definition and scope:

The National level record requirement for this field is Mandatory if applicable.

Field 100 is NOT repeatable.

Guidelines for applying content designators:

The content designators identify the subelements occurring in personal name fields constructed according to 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 field 650 (Subject Added Entry - Topical Term).

For indicator and subfield code definitions and examples, National-level (NLR) and Minimal-level (MLR) record requirements, and designator repeatability, see table below:

Content designator history:

First indicator - Type of personal name entry element

Values  1 - Single surname  [redefined]

2 - Multiple surname  [obsolete]

In 1996, the first indicator value 2 (Multiple surname) was made obsolete.  Value 1 (Single surname) was redefined as Surname to be used for headings with either single or multiple surnames.

Second indicator - Main entry/subject relationship  (BK MU SE)  [obsolete]:  The use of the second indicator in field 100 to indicate the main entry/subject relationship was made obsolete in 1990.  The values were:  0 (Main entry/subject relationship irrelevant) and 1 (Main entry is subject).

Subfield $g - Miscellaneous information  [changed, 2014]:  In 2014, subfield $g was made repeatable.

Subfield $j - Attribution qualifier:  In 2000, subfield $j was defined for attribution for names when the responsibility is unknown, uncertain, fictitious, or pseudonymous.

Subfields  $n - Number of part/section of a work  [defined]

$p - Name of part/section of a work  [redefined]

In 1979, subfield $n was defined for numbered parts/sections and subfield $p (Part) was redefined to include only named parts/sections.  Prior to that change, both the number and the name of a part were contained in one $p subfield.

Subfield $0 - Authority record control number  [new, 2007]

Subfield $0 - Authority record control number  [redefined, 2010]

Subfield $4 - Relator code  [renamed, 2017] [redescribed, 2017]:  Subfield $4 was renamed to Relationship and redescribed to allow for the recording of relationship URIs in addition to MARC and non-MARC codes.
