Two articles address the design of microcomputer networks and the use of local area computer networks (LAN) to improve library automation. Topics discussed include network design criteria, media for local networks, transmission mode, typical communication protocols, user interface, basic local network architectures, and examples of microcomputer…

Discussion of the use of inexpensive microcomputers in local area information networks (LAN) notes such minicomputer problems as costs, capacity, downtime, and vendor dependence, and the advantages of using LAN in offices and libraries, less costly LAN upgrades, library vendors and LAN systems, and LAN problems. A 28-item bibliography is provided.…
