RDA Option #4 : Match AACR2 & RDA bibs and flip to AACR2 heading

Some potentially exciting news.  We just added this new option to the mix and represents our true Option #4.  We had a client express interest in this option and our programming team put their heads together and made this available.

Option #4 will search your AACR2 or RDA bib headings against AACR2 authorities only.  So how is this any different from Option #1?  Option #1 ignores the 7XX x4 heading in an AACR2 authority record.  Option #4 will search that 7XX x4 authority in an AACR2 authority and then flip it to the 1XX main heading.  Option #4 will not search the separate RDA master authority file during processing.

This enables our clients to have their headings flipped to the AACR2 heading for all of their headings, whether AACR2 or RDA, but also allows the heading to be matched against that 7XX x4 heading.  Miracles can happen folks!

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.

Similar to Option #1, since we are not searching new RDA authority records, this heading will end up on our R07 Unmatched Primary Names report.

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, $d1956-

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 RDA 700 field in this AACR2 authority and will flip to the 100 heading:

bib

700         $a Cuadriello, Jaime.

Even though your bib heading (AACR2 or RDA) started out with a name-date, it matched on the RDA authority heading and then flipped to the AACR2 main heading.  In this scenario it loses the date from the name-heading, however it does represent the AACR2 authorized version.

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.

That 700 14 heading in the AACR2 authority would have also been checked in Option #4 had the 1XX heading not matched.
