Definition |
Subject added entry in which the entry element is a named event. Named events are those that cannot be regarded as responsible agents, e.g., battles, earthquakes, famines, financial crises, fires, hurricanes, riots, strikes, volcanic eruptions, wars, etc. Named events that 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. 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 2nd indicator position or in subfield ǂ2. For information about FAST (Faceted Application of Subject Terminology) subject access points, see 6xx Introduction. |
