FIELD DEFINITION AND SCOPE

Subject added entry in which the entry element is a named event.

Subject added entries are assigned to a bibliographic record to provide access according to generally accepted thesaurus-building rules (e.g., Faceted Application of Subject Terminology (FAST)). Field 647 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).

Named events are those which cannot be regarded as responsible agents, e.g., battles, earthquakes, famines, financial crises, fires, hurricanes, riots, strikes, volcanic eruptions, wars, etc.

Named events which can be regarded as responsible agents such as meetings or conferences as well as athletic contests, competitions, expeditions, expositions, fairs, festivals, sports events, tournaments, etc., are recorded in field 611.

INPUT CONVENTIONS

Punctuation - Punctuation of the subelements of a heading is generally dictated by subject heading system/thesaurus rules. These input conventions clarify MARC punctuation practices. An X47 field does not end with a mark of punctuation unless the field ends with an abbreviation, an initialism, or data that ends with a mark of punctuation.

Spacing - No spaces are used in initialisms, acronyms, or abbreviations. One space is used between preceding and succeeding initials if an abbreviation consists of more than a single letter.

Display Constant

- [dash associated with the content of subfield $v, $x, $y, and $z]

Dash (-) that precedes a subject subdivision in an extended subject heading is not carried in the MARC record. It may be system generated as a display constant associated with the content of subfield $v, $x, $y, and $z.
