Kevin is certainly correct about this, but I think a contributing factor in this misunderstanding is that various catalogers have been told repeatedly--whether accuately or not--that for many common materials, the differences _are_ minimal. Moreover this seems to have been done to calm catalogers' fears of having to change everything they do, especially if they are not in an academic setting or if they catalog mostly books and popular materials. I know I've been told this, sometimes as part of a what may have been intended as a comprehensive interpretation, sometimes as a throwaway line in a far less than comprehensive discussion. This muddled situation is one reason why I think the reaction from catalogers and library directors not involved in these discussions will be very negative, at least at first, if RDA is adopted.

Of course at that point we can always rely on our tried and true gambit of telling them that RDA, or at least cataloging change, has been in the works for years and no secret was made of it. this will allow us an approximate look at how many libraries and librarians willfully ignore discussions about cataloging even though their libraries still rely on it for finding and inventorying materials. I trust listmembers have archived their URLs for Dublin Core meetings from the 1990s and the rest of the references that pass for explanation and that have been bandied about on this and other concerned lists.

Anybody on this list wandered out to a nearby public library to ask about their plans regarding RDA? I'll concede that big publics like Chicago, Cleveland, et al., know about it--and New York Public manifestly knows about RDA--but what about the many other libraries that will be affected by whatever direction we go? I'm willing to bet that in many cases the answer may approximate the answer I got from our cataloging software vendor when I inquired about their plans: we don't know anything about that. Yet.

Subject: Identity of records, RDA vs. AACR2 (was: Policy Committee meeting outcomes (Clarification on Decision 2))

Bob Maxwell's post illustrates a very important issue that I think isn't being discussed that much.

The differences between RDA and AACR2 are not merely cosmetic.  Based on discussions on various lists, it seems some people think of the differences being mostly relatively minor details, such as the lack of abbreviations, whether certain elements are required or not, etc. etc.  Just as some people thought of the difference between AACR2 and AACR1 as mainly ISBD punctuation (I know of some catalogers who would add ISBD punctuation to a pre-AACR2 record and then code it as being AACR2--eek!!!)

AACR2 brought about significant changes to the entire basis of the description and access points:  two specific examples are more strict transcription of the title proper and statement of responsibility, and choice of main entry heading.  RDA represents a complete revolution in thinking about description and access.  For example, we are recording specific named elements, not just cobbling together "a record".  And, as Bob illustrates very well in his post, the entire nature of access points has been redefined, to make the data fit into the FRBR framework.

Just tacking on AACR2 headings to a description based on the RDA guidelines does not necessarily "an RDA record" make.
