Abstract
Computer‐aided systems for all four of the conventional divisions of the field of library housekeeping are now operational in libraries. In Great Britain the only activity not yet operational is that of periodicals control, although two libraries have already used a computer to produce lists of periodicals holdings. The aim of this paper is to describe simply how computer‐aided housekeeping systems work, from the point of view of the librarian, and to mention briefly some typical applications of each type of system.
