As catalogers begin making changes to existing AACR2 authorities and recode them as RDA (040 $e rda), it has consequences for our clients that are following any of our first 3 RDA options.
A quick refresher (RDA options):
1. AACR2 & RDA against AACR2 only
2. AACR2 against AACR2; ignore RDA bibs
3. AACR2 against AACR2; RDA against RDA
4. AACR2 & RDA against AACR2 (1st), RDA (2nd)
5. AACR2 against AACR2 (1st), RDA (2nd); RDA against RDA (1st), AACR2 (2nd)
The authority record for “Aristotle” (AACR2) was updated on July 18, 2012 with 040 $e rda as well as a few other changes [n 79004182]. Due to the 040 $e rda being added, however, that suddenly placed that authority (and others like it) out of the grasp of our clients that do not have us checking RDA authorities during matching.
So if you have an AACR2 heading with “Aristotle” it will be listed as unmatched in our system, assuming we’re using one of the 3 options listed above. In order to catch these scenarios, our recommendation is to change any client currently on Options 1-3 to Option 5 instead.
We plan to enact these changes to your settings over the next several days. If you would prefer that we do not change your RDA option from 1,2, or 3 to 5 instead, please just let us know.
