Authority records in the LC/NAF that are in the process of being updated sometimes contain "change messages."  Change messages usually relate to LC workflow where they serve as a temporary indicator of what changes will be made to an authority record.  NACO participants do not normally create change messages; NACO participants may encounter these records when searching LC/NAF.

These records are identified by the Record update in process fixed field 008/31 b and a capitalized term "MESSAGE" in the 667 field followed by information regarding how the record will be updated.

When NACO participants encounter a record with a change message that is more than several months old, they should notify the LC liaison.
