4xx references: Linking References
Linking references can be personal, corporate, or geographic names.
Linking refers to the use of special coding in subfield w to indicate that the reference represents a link from the pre-AACR2 heading in use at LC at the time the switch to AACR2 took place. Such references can be made whenever the AACR2 heading differs in any way from the pre-AACR2 LC heading for the same person or body.
Linking references can be coded acceptable AACR2 form (wnna) or not an acceptable AACR2 form (wnnaa).
Do not confuse this coding with wnne, which can be used to indicate the previous AACR2 heading, when a heading already coded AACR2 is changed.
LC now considers linking references optional. Princeton will continue to code linking references only for acceptable AACR2 forms (wnna). This does not affect the obligation to search for and record all LC in RLIN headings in a 670 field.
If the pre-AACR2 LC heading is an acceptable AACR2 form, code a wnna linking reference, whether or not it differs from the heading in one of the primary elements of the name.
Example showing heading and linking reference only
400 10 wnnaaRobertson, Jane Victoria,d1902-
100 10 Ball, F. C.q(Frederic Cyril)
If the linking reference would normalize to the same form as
the heading or another reference on the same record, do not make
667 Old catalog heading: Bérard, Jean Antoine, 1710-1772
670 L'art du chant, 1984:‡bt.p. (Jean-Antoine Bérard)
670 LC in RLIN, Feb. 24, 1988‡b(hdg.: Bérard, Jean Antoine, 1710-1772; no usage)
For personal names only, if the pre-AACR2 LC heading is not an acceptable AACR2 form, make an equivalent (not linking) reference in AACR2 form.
