The information retrieval problem whose solution is presented here was posed by a technical library with limited budget and personnel. The solution, however, is quite general and is applicable to many different types of retrieval problems. Further, the method of solution makes it possible for many groups who have previously dismissed an information retrieval program s expensive and difficult (from a programming standpoint) to reconsider their position, for the present solution makes it possible to install an information retrieval program in less than three months, and with relatively little equipment.
