Field definition and scope:

Field 710 contains a corporate name that is equivalent to the name contained in the 110 field of the same record.  It links headings within a system or from different thesauri or authority files.

The National level record requirement for this field is Optional.

Field 710 is repeatable.

Guidelines for applying content designators:

The content designators identify the subelements occurring in a name or name/title heading that contains a corporate 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)].

A corporate name, a form subheading, a title of an item or a series, 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 the X51 fields.

For non-subject purposes, other names used alone are contained in the X10 fields.

A named meeting that is entered directly under a corporate name is contained in the X11 fields.

Corporate names used in phrase subject headings (e.g., Catholic Church in art) are contained in the X50 fields.
