As promised, we are now ready to change over from our previous 7 options to our new 5 options for handling your AACR2 & RDA headings in authority control. The older 7 options included the possibility to match against 7XX-4 headings in AACR2 authorities and potentially flip to those same headings. The revised 5 options completely ignore the 7XX-4 headings in AACR2 authorities entirely. PCC will eventually expunge these fields from existing AACR2 authorities, so we wanted to be ready for that eventuality now. Although the majority of our clients have chosen / been assigned Option #1 (which did not change), this change from 7 to 5 will affect those clients that have chosen some of the later options. http://ac.bslw.com/community/wiki/index.php5/RDA_2.4 1. AACR2 & RDA against AACR2 only 2. AACR2 against AACR2; ignore RDA 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) In each of the cases above, we are matching against the 1XX and 4XX in the respective authority file (AACR2 or RDA) and flipping to the 1XX version of the heading. Options #1 & #2 remain as they have always been. Options #3 & #5 are similar to the older version counterparts, except now the 7XX-4 is taken out of consideration. Option #4 has added RDA as a second step for matching on RDA records as that seemed to make more sense in this context. The above link goes into more details about each of these options. We have also put together a detailed table listing what is matched against for each controlled access point within your bib record: http://ac.bslw.com/community/wiki/index.php5/RDA_Matching_Options No further action is required on your part. If you had chosen one of the prior 7 options before, we have moved those of you from the obsolete options over to the new options. As always, we welcome your feedback so please let us know any questions or concerns you may have.
