GUIDELINES FOR APPLYING CONTENT DESIGNATORS

Content designators identify the subelements occurring in a name or name/title heading that contains a personal name constructed according to generally accepted cataloging and thesaurus-building rules (e.g., Anglo-American Cataloguing Rules (AACR2), 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.

Only generally-applicable content designators are described in full in this section. A small number of content designators with field-specific instructions are described in the Tracings and References-General Information section (for field 400 and 500) and the 7XX Heading Linking Entries-General Information section (for field 700).

INPUT CONVENTIONS

Ambiguous Headings - See Appendix D: 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. An X00 field does not end with a mark of punctuation unless the field ends with an abbreviation, an initial/letter, or data that ends with a mark of punctuation.
