NOTES ON FIELD CONTENTS

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 608. The search is simultaneously performed through fields 608 and 968.

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 608 is linked to a corresponding field 968 by entering the same number (01–99) in subfield 6 of both fields. If more than one field 968 corresponds to a field 608, enter the same number in subfield 6 of all corresponding 968 fields.
