Catalogers are responsible for doing name authority work at the point of cataloging.
An authority record will not necessarily be needed for each heading. If a record is found, be sure that it matches the heading for the piece in hand. When in doubt, consult Superviser. Check the coding in the fixed field. If no record is found in the OCLC authority file, a local record must be created if you need a cross-reference, or it is a 'nauth' name.
