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
