As a result, a study program was initiated to identify the functional characteristics of a console ideally suited for augmented-catalog experimentation. Space does not permit a full exposition of the study program. The program involved an investigation of the reactions of various types of users to the terminal facilities serving present time-shared computer utilities, for ex- ample, Project MAC, and some experimental special- ized computer-based information networks, for example RECON 7 and TIP. 8° The program also involved an investigation of promising relevant new technologies and discussions with many people as regards their thoughts on the input/output requirements of a computer-based library system. The most important items considered in this study program were: (1) the user community that will be served by the augmented-catalog, (2) the type of data that will be contained in the augmented catalog, and (3) the operation of the computer-based library system. The salient points of each of these general considerations are now discussed. The interested reader can find greater detail in references 1_4. Results of the experiments performed on the console system described here will be reported by Project Intrex as they become available.
