Okapi: a prototype online catalogue

This article is a continuation and expansion of, which reported on an early stage of 'Microcomputer networking in libraries', a project funded by the British Library Research and Development Department and the Department of Trade and Industry. The work was carried out at the Polytechnic of Central London (PCL) by Mitev, Venner and Walker; its main aim was to construct a prototype online public access catalogue (OPAC) using local area network (LAN) hardware. The hardware was a Nestar PLAN 4000 network, using Apple IIe microcomputers as work stations and a 137 megabyte Winchester disc controlled by a 68000-based file server.
