Name Authority File or appropriate cross-references provided thereto.
Authority records are the correct forms of names, series or subjects used in the catalog.
The purpose of the authority file is to facilitate access to entries. Any automated system which is purchased should have the capability to implement authority control. All new automated systems should have the capability for authority control. While libraries do not have to implement authority control, they are strongly encouraged to do so. It is expected that libraries will buy a system that is MARC based and fully integrated.
