Corporate name used as a subject added entry.

Subject added entries are assigned to a community information record to provide access according to established subject cataloging principles and guidelines. Field 610 may be used by any institution assigning subject headings based on the lists and authority files identified in the second indicator position or in subfield $2 (Source of heading or term).

A corporate name, a title of a work, and/or a city section name entered under the name of a jurisdiction are contained in 610 fields. A name of a jurisdiction that represents an ecclesiastical entity is contained in a 610 field. Other names of jurisdictions used alone or followed by subject subdivisions are contained in 651 fields.

Description of the first indicator position and all subfield codes, as well as input conventions for the 610 field are given in the X10 Corporate Names-General Information section. Because the second indicator is different for various fields, it is not described in the general information section, but is described below.
