CONSER members may delete authenticated records if they are able to determine that the record was input erroneously.  This could happen when the title is determined to be a monograph or an integrating resource or is covered by another serial record.  Report the record to LC for evaluation and deletion when LC has holdings.  Send questions about LC serials bibliographic issues to Les Hawkins, CONSER Coordinator (conser@loc.gov); send questions about the process of deauthenticating a record to John Levy, Automated Operations Coordinator (jlev@loc.gov)).  Once it is clear that the record should be deleted, the duplicate record must be deleted from the CONSER database distributed by the Cataloging Distribution Service (CDS). Although non-LC CONSER records are no longer added to LC's local ILS, all CONSER records are distributed through CDS and duplicates must be deleted through the following steps:

1.  Lock the record in OCLC.

2.  Add field 012 $z d.

If field 012 is already present, add only $z d.  If subfield $b is also present in field 012, set the value to "3."

3.  Replace and relock the record.

4.  Remove field 042.

5.  Add field 936 "RECORD REPORTED FOR DELETION--USE # ..."

6.  Replace record and delete holdings.

7.  Report the record to OCLC for deletion.

8.  Record canceled LCCN in subfield $z of field 010 of record being retained.

It may be determined that the record is a valid duplicate in OCLC and can remain in the system.  Do not include field 936 "RECORD REPORTED FOR DELETION--USE # ..." nor report it for deletion, but complete the following steps:

1.  Lock the record in OCLC.

2.  Add field 012 $z d.

If field 012 is already present, add only $z d.  If subfield $b is also present in field 012, set the value to "3."

3.  Replace and relock the record.

4.  Delete fields 012, 042, 850.

5.  Replace record and delete holdings.

(It is no longer necessary to move LCCN to 010 $z.)
