FIELD DEFINITION AND SCOPE
Subject added entry in which the entry element is a geographic name.
Subject added entries are assigned to a bibliographic record to provide access according
to generally accepted cataloging and thesaurus-building rules (e.g., Library of
Congress Subject Headings (LCSH), Medical Subject Headings (MeSH)).
Field 651 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).
Jurisdiction names used alone or followed by subject subdivisions are contained in 651
fields. A name of a jurisdiction that represents an ecclesiastical entity is contained
in a 610 field. 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 contained in 610 fields.
Geographic names used in phrase subject headings (e.g., Iran in the Koran) are contained
in 650 fields.

INPUT CONVENTIONS
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. Field 651 ends with a mark of punctuation or a closing
parenthesis. If the final subfield is subfield $2 or $3, the mark
of punctuation precedes the subfield.
