OCLC control numbers and data sync records

  • If your records have the OCLC control number in field 035 $a with the (OCoLC) prefix, it will be used for matching.
  • If your records contain no OCLC numbers at all, data sync will use other elements in your records to select a match.

 Note: If you ordered your own records returned with OCLC control numbers merged into the records (in the OCLC Number Location(s) field [Bibliographic Record Information accordion > System tab]), the control number will appear in the field 035 $a.
