CONSER members may modify LC-authenticated records to maintain accuracy and to describe significant changes (e.g., ceased publication).

Key indicators of an LC-authenticated record:

050 is present and has second indicator "0", and

040 includes "DLC", and

010 is present and has an LCCN in subfield $a, and

042 is present and has some valid authentication code other than "nlc" or "isds/c".

Full, Associate, Enhance, and Affiliate participants obtain from OCLC a CONSER national level log-on authorization that permits making updates to all CONSER records.

In general, necessary changes to LC-authenticated records may be made without first notifying LC.  Certain categories of change that affect distribution of holdings, however, may require notification.

The following chart specifies the additions, changes, and deletions to LC-authenticated records that may or may not be made by CONSER members and the situations in which LC must be notified.  See also C8, C9, and C10.
