The message from University of Minnesota states that " clearly flagging headings needing review will greatly aid in training cataloguers and in giving them the confidence to work efficiently in a mixed RDA and pre-RDA environment."

This argument is circular. IF it is important for catalogers to follow RDA and associated LCPS and PCC policy to the letter and in all points, then it will be helpful for the LCAF to be as pure RDA as possible. However, some have claimed that RDA is user centered and allows room for judgment. It would be possible to see RDA, not as the final arbitrator of every last abbreviation, capital letter and $c in personal names, but as one representation of the evolving cataloging practice that has resulted in a very hybrid but still usable body of work. Not only descriptive conventions, but subject headings and classification are continually changing, and as long as consistency is maintained for the treatment of any given name or topic, the fact different headings and records were created under different flavors of rules need not be a problem. Though some important principles in establishing headings changed with AACR2, most changes have been small and evolutionary, rather than revolutionary. (Though RDA may be theoretically revolutionary, the MARC records that we are still bound to look pretty much the same.)

If we could take RDA as a guide rather than something bordering on scripture, and let "optional" mean "at the option of the cataloger" rather than "up to LC and PCC to rule on" it would be simpler to train catalogers. If we were not so concerned with being sure that authority records were carefully labeled as RDA-compliant or not, we would have more time to collectively create more authority records, which regardless of the exact rules, rule interpretations, policy statements and group deliberations that were used to create them, all function to distinguish names from one another and to lead users to resources.

Subject: Re: [PCCLIST] Alternates for the RDA conversion

At the University of Minnesota we have also discussed the alternative proposals and we generally find ourselves in agreement with the University of Washington's position, and in particular with the first four points expressed in Joseph Kiegel's April 20 message.

We recognize that system capacity is a genuine concern for many institutions. We have heard discussion elsewhere of a possible compromise approach that we believe deserves serious consideration.
This is to make all of the changes originally proposed to the LC/NACO authority file but to distribute only a subset of the changed records.
This may be one of the subsets proposed under scenarios 1-4, or perhaps it may be possible to offer individual institutions a choice among them. Records not reissued at this point could be reissued on a future schedule, or upon being changed in some other way.

Institutions with a limited capacity to absorb changes would not be disadvantaged by this approach as compared with any of the limited redistribution scenarios, but the benefits of having a comprehensively updated central authority file would be preserved.

Whatever solution is adopted, we think it will be valuable to make the status of headings explicit. As a minimum, records with 1XX headings not usable under RDA without review should be labelled with a 667 field, as proposed under scenario 2 (as well as in all of the more ambitious scenarios). While it is true that users will not care if a heading is RDA-compliant, we think that clearly flagging headings needing review will greatly aid in training cataloguers and in giving them the confidence to work efficiently in a mixed RDA and pre-RDA environment. Because the LC/NACO authority file is available to be consulted online, these changes would be of benefit to cataloguers even if the records in question are not redistributed.
