Guidelines for applying content designators:

The defined content designators identify the subelements occurring in corporate name fields 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 a work, 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 (Subject Added Entry - Geographic Name).

For non-subject purposes, other names used alone are contained 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 (Subject Added Entry - Topical Term).

The indicators, subfield codes, and input conventions for the corporate name fields 110, 410, 610, 710, and 810 follow similar patterns.  Guidelines for applying the first indicator and subfield codes are below.  Subfields are grouped by type of entry.  See the specific field for the second indicator information.

For indicator and subfield code definitions and examples, National-level (NLR) and Minimal-level (MLR) record requirements, and designator repeatability, see table below.  An asterisk ( * ) in the column indicates that the requirement varies.  See table in the specific field.:

Input conventions:

Subfields  $c - Location of meeting  [new]

$d - Date of meeting or treaty signing  [new]

The location and date of a meeting and the date of signing of a treaty entered under a corporate body or jurisdiction were not separately subfield coded but included in subfield $p prior to the definition of subfields $c and $d in 1980.
