Cross-references (4XX and 5XX) [New]
Add required cross-references to the authority record, including tags, subfields, delimiters, and diacritics. Search all cross-references to ensure they do not conflict with established authorized access points (1XX). A cross-reference (4XX) may conflict with a 4XX on another record. Keep in mind that normalization may result in conflicts between the authorized access point and 4XX forms of the name on the same NAR or other records. Such conflicts must be resolved.
Cross-references are formulated according to the same guidelines and instructions as authorized access points.
Apply the guidelines in RDA and the associated PFAN PSs when formulating cross-references.
Do not record a "see" reference (4XX) that would normalize to the same form as the 1XX in the same record or to the same form as the 1XX or 5XX in another name authority record. "See also" references (5XX) must be in the same form as their corresponding authorized access points.
Do not add references solely for automatic conflict detection and updating of bibliographic records. Inherent in the PFAN principles is the goal of making all cataloging workflows more efficient; since its inception the PFAN has recognized the need to have a file that is easily and efficiently used by all. This goal can only be achieved by an authority file that is uniform, i.e., predictable, in its construction and formulation of access points and references. Given the nature of the Program, it is impossible for the shared authority file to meet the database maintenance needs of each individual library. Catalogers are allowed to use judgment in making additional references and under RDA variants are not core, but the expectation is that those references would be constructed in the form consistent with the standard cataloging rules, practices, and policies currently used by all PFAN participants.

Simple 4XX "see" cross-references [New]
Variant access points are not core elements under RDA, and the AACR2/LCRI requirements for them no longer apply.
Nevertheless, the following guidelines represent PFAN best practice in the RDA environment. They are based on requirements that existed under AACR2.
Variant access points (4XX) should be justified by citation in the 670 or as required by RDA and the PFAN PSs.
NACO participants are no longer required to record linking references from pre-AACR2 headings found on bibliographic records.
References from former authorized access points are recorded with the following subfield: 4XX $w nne
This indicates that the cross-reference was formerly a fully established, valid AACR2 or RDA access point and its form is valid under RDA. The 4XX must match the former 1XX in the record.
A reference from a former authorized access point that is not valid in form under RDA, e.g., because it contains an abbreviation that is no longer allowed, is recorded with the following subfield: 4XX $w nnea
The ending value “a” in subfield $w nnea causes the reference to be suppressed and not displayed in most systems.
Use of subfield $w nnea is recommended when providing a reference from a former authorized access point with an open date, when the authorized access point is updated to close the date:
Because each element in the hierarchy of an access point must be in the established form, variant access points must sometimes be given in a mixture of languages. Other forms can be given in a single subfield based on usage, if considered useful.
Record a reference from each variant that affects the primary elements of the name. Generally, this means variations in all elements to the left of the comma and in the first element to the right of the comma.
Refer from other variants (i.e., those that do not affect the primary entry elements) when it is judged that access to the catalog would be improved, as in the case of differing search strategies in other databases. For example, additional cross-references may be given for variants with common surnames.
Generally, provide one reference from each possible entry element of the name chosen as the authorized access point.
Generally, make only one reference from each variant. When in doubt, generally do not provide references for “variants of variants.”
In references with initials, the full form may be added in subfield $q, if considered important for identification.
In the example above, since "John Smith" is a very common name, it is a good idea to record this cross-reference even though the primary elements are the same in the 100 and 400 fields.
Include additions in the reference if appropriate to the form of the reference. Certain additions may be inappropriate in the authorized access point and/or reference. Additions may be made to a reference consisting solely of an initialism.
