610 Subject Added Entry - Corporate Name (R)

See the specific field for its repeatability.

Guidelines for applying content designators:

The defined content designators identify the subelements occurring in corporate name fields. A corporate name, a title of a work, event, program, etc., and/or a city section name entered under the name of a jurisdiction are X10 corporate names. A name of a jurisdiction that represents an ecclesiastical entity is an X10 corporate name. For subject purposes, other names of jurisdictions used alone or followed by subject subdivisions are geographic names and are contained in field 651. For non-subject purposes, other names of jurisdictions used alone are contains in 110 and 710 fields.

A named meeting that is entered under a corporate name is contained in the X10 fields. A meeting entered directly under its own name is contained in the X11 fields. Corporate names used in phrase subject headings (e.g., Catholic Church in art) are contained in field 650.

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 X10 field.
