Field Definition

Occurrence

Optional. Any number of linking fields may be included in a record. For certain categories of linking fields (notably 46- Level linking fields) there is a restriction on the type of link which may be made. Details are given in Notes on Field Contents for such fields.

Indicators

Indicator 1: blank (not defined)

Indicator 2: Note Indicator

The second indicator indicates whether the agency providing the record would use the data in this field to make a note for print or other displays of the record. If a note is not required, this indicator should be set to 0 (EX 1, 4, 6). The kinds of notes envisaged being created using this data are illustrated in the examples (EX 2, 3, 5). When the record is displayed, the specific field tag may be translated into text that describes the exact relationship of the item to which the link is being made and the item being catalogued: the exact wording of the text depends on the practices of the agency receiving the record.
