2A CATALOGING IN RDA

2A CATALOGING

This statement is in response to questions stimulated by 2A cataloging done under RDA.  2A cataloging is a cataloging technique applied to certain unnumbered (or, rarely, partially numbered) multipart sets classified as a collection and not analyzed.  Such materials are judged of significance primarily as a group; individual items are not considered significant enough to catalog separately.  Though the set is "made up" because the individual items lack numerical designation, the individual items in the set are usually closely related by subject and other strong similarities, such as title (or parts of title), issuing body, or publisher.

With respect to the inventory aspect of 2A cataloging under RDA, we want on the one hand to make it clear in the bibliographic record the state of the material as it was issued by the publisher but on the other hand to state clearly the rearrangement/repackaging that LC has done.  Thus, the extent statement (300 $a) expresses the number of volumes as issued by the publisher, and a copy-specific 500 note expresses the rearrangement done by LC.

Example illustrating complete 2A set (LCCN 2011308398):

300 ## $a 7 volumes : $b chiefly color illustrations ; $c 22 x 28 cm
500 ## $a LC copy bound together in 1 volume subsequent to publication.
          $5 DLC
Enum. area of item record: v. 1-7

Example illustrating complete 2A set (LCCN 2011311219):

300 ## 14 volumes : $b illustrations, maps ; 25 cm
500 ## LC copy bound together in 2 volumes subsequent to publication. $5 DLC
Enum. area of each item record: v. 1, no. 1-7
                                v. 2, no. 8-14

Note that in this example illustrating the LC rearrangement that is itself in more than one volume, the contents note must be done in such a way as to show the contents of each of the LC volumes.

Example illustrating a 2A incomplete multipart monograph (LCCN 2011308239):

264 #4 $a Quezon City, Philippines : $b Precious Pages Corporation, $c 2009-<2010>
300 ## $a volumes ; $c 18 cm
500 ## $a LC copy bound together in 2 volumes subsequent to publication.
          $5 DLC
Enum. area of each item record: v. 1, no. 1-3
                                v. 2, no. 4-6

Note that 264 subfield $c indicates the incomplete state of the set, only a generic extent is recorded in 300 $a while the set is still in progress; specific holdings are recorded in the holdings and item records.  However, note that the copy-specific 500 note is updated as more volumes are added to keep the information about the number of bound volumes accurate.

Example illustrating the binding together of a multipart monograph for reasons of economy          (LCCN 2011308247):

300 ## $a 6 volumes ; $c 17 cm
500 ## $a LC copy bound together in 1 volume subsequent to publication.
          $5 DLC

Enum. area of item record: v. 1-6

040 - Cataloging Source - MARC

Add subfield $d {MARC 21 code} when modifying NARs or SARs unless your institution's is already the last MARC subfield $d in the 040 field.

For example if LC is modifying agency, when making revisions to a NAR, we should add a $d DLC to the 040, if that is not the latest subfield present.
