[DCRM-L] OCLC migration from 260 to 264

[Noble, Richard]

>From a message sent by our head of cataloging:

Globally, OCLC intends to add 336/337/338 to all OCLC records containing a
245$h.  In March 2016, they plan to eliminate the gmd altogether.  They
also plan to migrate from 260 to 264 in cases where the change can be
automated.  There may be other changes as well to pre-RDA records.

I don't suppose that there is much mischief involved in ditching the gmd,
 but is there the possibility of irreversible information loss in migrating
data from 260 to 264, as in the case of the global abbreviation of 250 data
a while back? Is this possibly a case where records tagged dcrmb are or
should be exempt?

On the other hand, if it's only a matter of retagging 260 ## $a/b/c as 264
#1 $a/b/c, and  migration of 260 ## $e/f/g to 264 #3 $a/b/c, without change
of content, then no harm done--one hopes.

Several catalogers have noticed the MARC fields 336/337/338 and 264 showing
up in AACR2 records.  You may also encounter pre-RDA records with
certain abbreviations spelled out.  This is perfectly acceptable and the
new fields, etc. should be left alone unless they contain an error.  Please
do let me know if a new field or subfield shows up as invalid.

Globally, OCLC intends to add 336/337/338 to all OCLC records containing a
245$h.  In March 2016, they plan to eliminate the gmd altogether.  They
also plan to migrate from 260 to 264 in cases where the change can be
automated.  There may be other changes as well to pre-RDA records.

In our own database, we have begun adding 336/337/338 to e-resource
records.  We have also asked Serials Solutions and YBP to add 336/337/338
to incoming, non-RDA e-resource records.

By themselves, such changes do not justify re-coding a record as RDA.
