DCM Z1: 5XX See Also From Tracings - General Information
General:
When otherwise modifying a NAR that contains codes that are no longer used such as subfield $w position zero (0) code d or f, LC/PCC catalogers should upgrade the NAR to RDA.
LC/PCC catalogers applying RDA instructions may use subfield $i (Relationship information) in conjunction with subfield $w code "r" for relationship designators. When applying RDA relationship designators in 5XXs, supply terms from Appendix I, J or K; capitalize the initial letter of the term and follow the term with a colon.
For information on the use of relationship designators and/or $w codes in a specific 5XX field, see the specific DCM Z1 section for that field.
Subfield $w - Control subfield:
Follow the conventions in the authority format for use of subfield $w. Do not supply subfield $w unless a value other than n would be appropriate in one of the positions. When supplying subfield $w, give it as the first subfield in the field. Supply character positions preceding, but not succeeding, the value, e.g.,
$w a = to indicate a reference from an earlier authorized access point
$w b = to indicate a reference from a later authorized access point
$w r = to indicate that a subfield $i or subfield $4 is used to denote relationship information
$w nnnc = to indicate a see also reference for multiple pseudonyms (record also contains a 663 field)
NARs:
A see also reference tracing (5XX) must not normalize to the same as another see also reference in the same authority record, unless both 5XX fields contain a relationship designator in subfield $i, and the texts of the relationship designators are different.
