Character position definition and scope:

A one-character code that indicates the creator of an authority record.  If the cataloging source is known, it is identified in subfield $a of field 040 (Cataloging Source).  The parties responsible for the MARC authority record are determined by the code in 008/39 and the MARC code(s) or name(s) in field 040.  The fill character ( | ) is used when no attempt has been made to code this 008 position.

National Level Requirement for character position 008/39:  Mandatory; for codes below:  Mandatory if applicable.
