This study assesses the application of both minicomputers and microcomputers to information-handling procedures and makes recommendations for automating such procedures, particularly in developing nations. The report is based on a survey of existing uses of small computing equipment in libraries, archives, and information centers which was conducted from October 1979 to May 1980. Following a description of report aims and layout, a discussion of the impact of computer technology on information handling traces the history of the relationship between computers and information systems and outlines historical changes that have occurred in computer technology. Examples given of small-scale computing equipment usage in information handling deal primarily with microcomputers and include unusual projects. Other chapters clarify terminology and formulate definitions, identify basic components of minicomputer systems in terms of equipment selection criteria, discuss current trends in information systems and services development, and predict changes which will affect information handling. The effect of these changes on information professionals and educators is considered, and recommendations are made for further investigations, education and training requirements, and standards for systems and documentation. Report annexes provide background detail and deal with terminology, minicomputer manufacturers, and microcomputer systems. (Author/LMM)
