ABSTRACT
The infrastructure for systems for the organization of knowledge has three components: databases, hardware and software. All of these three components need to be designed and maintained. Business organizations will take responsibility for performing these activities in relation to the transaction and management information systems that underpin the effective operation of the organization. This chapter explores some of the key measures that can be used in the evaluation of the success of information retrieval, and then briefly identifies the approaches available to performing evaluation. Users, information professionals and others involved with the design and maintenance of such systems need to manage that change. Authority control consists of the creation of authority records for established headings, the linking of authority and bibliographic records, and the maintenance and evaluation of an authority system. Typically, this involves attention to day-to-day maintenance issues and system integrity, security and user support.
