The Textile Information Retrieval Program (TIRP), a study made at the Massachusetts Institute of Technology to develop an interactive information retrieval system operating on a time sharing computer, was demonstrated to and operated by research scientists, information specialists, and numerous other persons at North Carolina State University at Raleigh. The purpose of these trials was to study the interaction of the users with this system and the equipment associated with it and to compare, insofar as was possible, these operations with those of a batch processor retrieval system, using essentially the same data base, operated by the North Carolina Science and Technology Research Center. Approximately 60 searches were conducted in the trials and demonstrations with the cooperation of about 45 representatives of industry and the universities. These trials indicated that TIRP responded more favorably to the simultaneous efforts of information specialists and scientists assisted by expert typists. It is concluded that future developments and extensions should come from the joint efforts of the universities and the textile and fibers industries in order to insure that any subsequent system is both simple in conception and practical in operation.
