LC Guidelines: 005 Date and Time of Latest Transaction
NACO:
A NACO participant system may supply a preliminary 005 field to new records which will be replaced by the first official 005 at LC when the record enters the National Authority File.
An 005 field is system generated by LC when a NACO record is added to the National Authority File at LC whether there is already an 005 field in the record or not. For a record new to the National Authority File, the 005 generated is the first official version identifier for the record. A change record must contain an 005 identical to the one in the National Authority File record it is changing for the change to occur. The 005 is automatically updated when the change record replaces the record in the file.
SACO:
