Matt -- CONSER catalogers have been instructed to use and authenticate
existing records when they exist rather than creating new records.  Here
are the specific instructions from the CONSER working procedure at
http://www.loc.gov/acq/conser/agg-neut-inst.html

Hope this helps.  --Steve

Multiple Records, Record Modification, and Deleting Duplicates

If multiple records exist for a title describing it as a part of several
aggregator packages, one record should be selected for CONSER
authentication and others reported for deletion.

* Select one record, to maintain, prefer a CONSER record if one is
available. If there are multiple CONSER records, prefer a record
authenticated by NSDP or ISSN Canada

* Add the URL of the aggregation for which you are providing access and/or
copy URLs from the records you are reporting for deletion and record them
on the record you are keeping.

* Remove fields that are aggregator specific, e.g. 710/730 or 440 for
aggregator names; notes which only apply to one aggregator.

* CONSER authenticate the record if it is not a CONSER record, report the
other records as duplicates.
