a  Core record designator (NR)


Field 039 is used to indicate that a record has been created at the core level, as defined in CEG B6.  Use of field 039 is an interim measure until encoding level "4" is fully implemented by OCLC.

Field 039 is not distributed.  On output, OCLC converts 039 $a to Leader/17 (encoding level) value "4."

Prior to March 1996, the word "core" was input in field 040 $e.
