RDA Option #1 : Match RDA bibs as if they are AACR2 bibs This option requires no input from our clients in order to be applied, which is why we considered it as our default choice. We realize while some of our clients are very interested in exploring different RDA processing options, other clients are more interested in making sure the service continues to work as expected. Since RDA is in flux during this testing phase, rules can change frequently and perhaps it makes sense to instead stick to the status quo and address RDA concerns at a future date. With this option, your bib records are treated as if they all are AACR2 bib records. Even if you have a bib record with “040 $e rda”, which our system would identify as an RDA bib record, this option will tell our system to ignore that designation. The same processing, cleanup, validation, and heading matching you’ve set up using our online profile will apply to every bib record received from you. Example #1 You have a bib record with the following fields: bib 245 04 $a The principal’s guide to curriculum leadership. 260 $c 2011, c2011. 700 $a Méndez, Zulma Y. There is no AACR2 authority that exists for this 700 heading. However, there is an RDA authority (created Oct 4, 2010): authority 001 n 2010063506 040 $a DLC $b eng $c DLC $e rda 100 1 $a Méndez, Zulma Y. What will happen to this heading within your bib record? Since you have chosen Option #1, this bib heading will end up in our R07 Unmatched Primary Name report as the RDA master authority file is not checked for this option. Example #2 You have a bib record with the following fields: bib 245 00 $a Glories of the Republic of Tlaxcala, 2011. 700 $a Cuadriello, Jaime. There is an AACR2 authority that exists for this 700 heading (updated on Oct 7, 2010): authority 001 n 00010585 100 1 $a Cuadriello, Jaime. 700 14 $a Cuadriello, Jaime, $d 1956- Your bib heading will match on the 100 field in this AACR2 authority and so will remain: bib 700 $a Cuadriello, Jaime. So that 700 14 heading in the AACR2 authority is ignored in Option #1. Example #3 You have a bib record with the following fields: bib 245 00 $a Inside Microsoft Windows 2000. 260 $c 2000. 700 $a Russinovich, Mark E. There is an AACR2 authority that exists for this 700 heading (updated on Oct 19, 2010): authority 001 n 00010996 100 1 $a Russinovich, Mark E. 700 14 $a Russinovich, Mark E. Your bib heading will match on the 100 field in this AACR2 authority and so will remain: bib 700 $a Russinovich, Mark E. So that 700 14 heading in the AACR2 authority is ignored in Option #1.
