This manual based on Menlo Park's experiences in participating in a nationwide experimental computer literacy project provides guidelines for the development and management of a ComputerTown. This project, which was begun in September 1981 in the Menlo Park Public Library, concentrates on providing public access to microcomputers through hands-on computer experiences for the new to intermediate potential user, and assisting them in becoming comfortable, aware, and informed about microcomputer technology. Advice on planning a ComputerTown covers administrative personnel, computer access, and local newspaper contact. Ideas are presented for offering introductory events, special workshops, and working with volunteers. Four typical events are profiled: a business night, computers at the Learning Faire, a Word Processing Study Group, and the ComputerTown Barrington (Illinois) Conference. Typical user questions and advice on personal computer selection are included. A description of courses and other learning activities includes user validation, games and programming, sample course titles and curricula, ComputerTown Scrapbooks, peer teaching, host institutions, planning new ComputerTowns, and creating a formal organization. Appendices contain technical advice on handling resources, including physical arrangement, equipment handling, software storage and cataloging, copyright considerations, software security, and print materials.
