Early Notice Records (Additions and Changes to Authority Records)
Early Notice Records (ENRs) are brief, incomplete authority records input into the NAF as temporary records while the full records undergo the complete review and input process.
ENRs may be identified by the Encoding level fixed field Leader/17 o (i.e., lower case letter "o"). Some ENRs may not have any cross references, or may have an incomplete 670 field. Although the records are incomplete, the headings themselves should be considered valid and available for use.
An ENR can only be completed and upgraded into a full authority record by the library that created it. If a NACO participant has more information or cross references to add to an ENR, he should wait until the full reocrd appears and judge whether the additional information is necessary. If so, update the record per usual procedures.
When a NACO participant encounters an ENR that is more than six months old, he should notify the NACO Coordinator, who will then ask LC staff to check on the record.
