This field is used for entering variant forms of those subject headings that are not linked to authority records. Enter the forms that differ from the form in field 605. The search is simultaneously performed through fields 605 and 965.
The subfield 6 – Linking data must always be filled in, since it is used to link all forms of a subject heading (see examples 1, 2). Field 605 is linked to a corresponding field 965 by entering the same number (01–99) in subfield 6 of both fields. If more than one field 965 corresponds to a field 605, enter the same number in subfield 6 of all corresponding 965 fields.
