AACR2 Authority Records Policy: GPO will not apply AACR2 or LCRIs to any cataloging of authority records. All new name authority records (NARs) must follow RDA. As soon as a cataloger encounters a non RDA acceptable record that is needed for a bibliographic record, he/she must recode that record to RDA. AACR2 and LCRIs are irrelevant to this task. Furthermore, as soon as a cataloger needs to update any AACR2 (or earlier code/rules) record, he/she must recode that record to RDA. Again, AACR2 and LCRIs are irrelevant. The only exception is when a record is being updated only to change a 5XX field, in response to changing a 1XX in another record. In this situation, the cataloger is only making a mechanical change in the 5XX field, and there is no need to apply any knowledge of AACR2 and LCRIs. Finally, in the situation where a cataloger is using an RDA acceptable name authority record (coded AACR2) as an access point in a bibliographic record, the cataloger makes no changes to that name authority record. Again, there is no need to apply any knowledge of AACR2 and LCRIs.

 

With authority work, all emphasis shifts to the current standards: RDA and the associated LC-PCC PSs. Whenever evaluating, modifying (updating), or re-coding (upgrading) an NAR, the cataloger must consult RDA/LC-PCC PSs. This is especially true when evaluating an existing heading/authorized access point to determine if it follows RDA rules. The cataloger could, conceivably, consult AACR2/LCRIs, to determine if the heading complies with AACR2. But that will not tell the cataloger if the heading complies with RDA, and that is what the cataloger needs to know.

There is one notable exception: Treaties will be cataloged according to AACR2 and LCRIs. See: Name Authorities, RDA, Works and Expressions.

Field Specific Guidelines

5XX - See Also From Tracings

When applying RDA relationship designators in 5XXs, supply terms from RDA Appendix J or K; capitalize the initial letter of the term and follow the term with a colon (DCM Z1 5XX section). However, pre-existing 5XX references in AACR2 format (i.e., ǂw values without ǂi) do not need to be changed to RDA when updating or recoding the record. They are acceptable under PCC standards.

Example from an RDA record (Fixed Field/Rules = z, 040ǂe = rda):

110 1_ United States. ǂb Bureau of the Census

510 1_ United States. ǂb Census Office ǂw a

510 2_ U.S. Census Bureau ǂw b

ǂw: a = earlier heading, b = later heading
