Subject: Database Scans for Accm and Prme on OCLC
Sender: "Caplan,Ellen" <[log in to unmask]>



The following is some information for those of you that catalog cartographic
materials on OCLC.

In Update 3 (July 1997) to the USMARC Format for Bibliographic Data,
Accompanying Material (AccM) in Visual Materials and Prime Meridian (Prme)
in Maps were made obsolete.  In preparation for a future MARC Bibliographic
Update, OCLC plans to scan the fixed field and 006 elements to delete all
values other than 'blank'.  Initial scans will not be run until January or
February 2000.

For Visual Materials, there are approximately 140,000 records with values
other than 'blank' in the fixed-field element AccM.  The number of VIS 006
fields with values other than 'blank' in AccM is under 200.  For Maps, there
are approximately 12,000 records with a value other than 'blank' in the
fixed-field element Prme.  The number of MAP 006 fields with values other
than 'blank' in 'Prme' is under 150.

OCLC has not yet declared these elements obsolete.  You may continue to code
for accompanying material for Visual Materials and prime meridian for Maps.
However, OCLC's recommendation is to leave these elements coded as 'blank'.
Note that Accompanying Materials in Scores and Sound Recordings is not
affected.  The values in these formats for AccM are still valid.
