The LC/NAF contains headings designated "provisional" which may be identified by Level of Establishment fixed field 008/33 c.

Generally, these are authority records that could not be fully established according to the rules because of inadequate information about the person, corporate body, etc.  Frequently, this is because the language of a parent body and a subordinate body differ, or because the cataloger who established the heading did not have the language expertise necessary to establish it as a full-level record.

NACO members are expected to upgrade these records whenever possible.
