Project Intrex is a program of experiments intended to provide a foundation for the design of future information transfer systems, with the library of the future visualized as a computer-managed communications network. In order to discover the necessary facts, especially in the area of the user's interaction with the system, experimentation is being conducted in the environment of an operating library as well as in the laboratory. The initial efforts have been concentrated on the problems of access--bibliographic access through an augmented catalog, and access to full text. The efforts during the six months covered in this report have concentrated on the implementation of the experimental library information storage and retrieval system. The configuration of the initial system is defined in detail and the objective now is to bring it to a state in which it can be tested and evaluated as a complete system. This report presents details of progress being made on the development of (1) the augmented catalog of at least 10,000 journal articles, reports and theses in selected areas of materials science and engineering; (2) the augmented-catalog display console; (3) the storage and retrieval programs; and (4) the full-text-access system.
