GUIDELINES FOR APPLYING CONTENT DESIGNATORS

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).

Guidelines for applying all content designators except the second indicator position are given in this section. A field-specific list of content designators and guidelines for applying the second indicator position are provided under the description for each specific X00 field.

INDICATORS

First Indicator - Type of personal name entry element

Value that identifies the form of the entry element of the field. The values distinguish among forenames, surnames, and family names used as the entry element.

0 - Forename

Heading begins with a forename or is a name consisting of words, phrases, initials, separate letters, or numerals that are formatted in direct order.

INPUT CONVENTIONS

Ambiguous Headings - See Appendix E: Ambiguous Headings.

Punctuation - Punctuation of the subelements of a heading is generally dictated by descriptive cataloging or subject heading system/thesaurus rules. These input conventions clarify MARC punctuation practices. Fields 100, 600, 700, and 800 end with a mark of punctuation or a closing parenthesis. If the final subfields are subfield $0, $2, $3, $4, or $5, the mark of punctuation or closing parenthesis precedes those subfields.
