As computers assume an increasing prominence in library strategies and budgets, librarians must deal with the problems of purchasing appropriate equipment as well as maintaining it. This comprehensive how-to covers computers for public access and staff use in both PC and MAC formats. In language designed for librarians with all levels of expertise, it discusses hardware and software issues, security, and common repair tools, licenses, warranties, inventories, wiring, backup systems, preventive maintenance, costing, staffing, and vendors. All forms and checklists are available on the companion Web site.
