This directory contains information about current applications and proposed uses of computer systems in Florida's libraries for the purposes of (1) providing the base for a communication network among librarians now using computers and those who are interested in using them, (2) identifying information sources for librarians who are considering the use of computers, (3) suggesting possible applications of computers to library functions, and (4) computers for those persons responsible for pre-service and in-service education of librarians. Tables display the number of libraries of various kinds that are applying or planning to apply computer technology to major functions; that are using or planning computer applications developed in-house; and that are using externally-developed systems. The directory lists the address and telephone numbers for the providers of those systems. Descriptions of computer applications and the names of contact persons are given for individual institutions in four sections focusing on academic libraries, public libraries, school media centers, and special libraries.
