Every day, the Bibliographic Record Notification service compares all upgraded OCLC MARC records to the records your library has holdings attached to, and then sends you upgraded records based on a detailed profile that tells OCLC what updates are important to you. You receive new records by Data Exchange (EDX) or download them from the OCLC Product Services Web, then load the upgraded records into your system. Reports summarizing the type of upgrades and quantity of records being delivered are also available.

The Bibliographic Record Notification records are delivered in a separate file from your CatExpress records. The Bibliographic Record Notification records do not count toward overage on your CatExpress subscription and are not included in the statistics on your CatExpress activity reports.
