This report describes the current status of Project INTREX experiments and provides a detailed technical record. Activities concentrating on the bibliographic access problem involve: (1) the investigation of a digitally-encoded, machine-manipulated augmented catalog, for which the task of preparing entries for 10,000 documents is about half completed; (2) testing a user-oriented program for consulting the augmented catalog; (3) constructing a display console; and (4) developing an experimental transmission system for full-text access to the documents that have been cataloged. The computer-stored augmented-catalog part of the Experimental Library Storage and Retrieval System is now working satisfactorily for demonstration purposes. The augmented-catalog console and the full-text-access equipment are nearing completion and should be functioning early in the next reporting period. Recent emphasis has been on the software and on the design and construction of the interface and control logic associated with these items. (Author/JB)
