A review is presented of mechanized equipment, exclusive of the computer, being used in the housekeeping aspects of the four conventional fields of library endeavor: acquisition, processing, use, and maintenance of library material. Brochures were collected from manufacturers, library and office management literature was searched, and a questionnaire was sent to 1,000 selected libraries in the U.S. asking for information about machinery and techniques in use. There is not a large amount of equipment, other than the basic typewriter, being used in small and medium-sized libraries in the United States. Funds are not readily available for the purchase of equipment, and most of the current studies are on application of the computer to library processes. Much remains to be done before many of the smaller libraries will be able to take advantage of equipment now available. (Author)
