This study evaluates the economic and financial aspects of the application of teleprocessing and telecommunications to the transfer of scientific and technological information, especially in the context of developing countries. It was intended to facilitate comparison of the relative value of a teleprocessing network with that of other modes of information distribution. The study was restricted to networks of bibliographic information services in three regions: (1) Arab Region with Cairo as regional center, (2) South East Asian Region with Kuala Lumpur as regional center, and (3) Andean Region with regional center to be selected. Technical issues addressed include specification of requirements, technology and costs, network design, regional networks, economic considerations and comparative evaluations, and some specific information network problems with suggested solutions. A series of annexes document current experiences of information retrieval operations, including the role of intermediaries, development issues concerning the interface between humans and computers, international leased circuits, and annual costing for regional centers.
