Why automate? A formal needs assessment or a common-sense analysis may indicate that one or more of the library's functions should be computerised. This manual provides a basic guide to the essential steps and components of automation planning in medium-sized and smaller libraries. Emphasising current modular (often microcomputer-based) options, the authors lead the librarians through the entire process, from defining basic concepts and terms to establishing priorities, designing specifications, preparing RFPs and negotiating contracts.
