Authority work (or the checking and creating of name and subjects headings) is an important part of the cataloguing process. It is a way to distinguish name headings and to link the various names of an individual or group under one or more headings. Headings range from the simple to very complex, depending upon the name being established. Name headings are created to distinguish individuals or groups associated with catalogued materials. Authority records can also be created for subject headings and form/genre headings. This chapter will examine name authority records for both individual and corporate headings for the special collection materials such as those described in the foregoing chapters.
