General explanatory term from the index to the classification scheme that is identified in field 084 (Classification Scheme and Edition). Field 154 is appropriate only in an index term record (008/06, Kind of record, code c) that is created because the index term cannot be accommodated in a 70X-75X Index Term field in a schedule or table record (008/06, code a or b) that contains a classification number in field 153 (Classification Number). This occurs when the index term is not associated with one classification number or span. Field 753 (Index Term-Uncontrolled) is always used in a record containing field 154 to direct the user to different locations within the classification scheme for classifying the topic.
