In this article, the computer, library network, and telecommunications industries are examined and the state of the art briefly summarized. Several models for library network design are presented, with evaluations of the effectiveness of each model and recommendations for future action.
The automated authority system at the National Library of Canada was described in the December 1976 issue of JOLA. This paper explores actual and potential implications of system features such as the normalized key, and the ability to store and control authorities for multiple languages, applications, and libraries with respect to National Library cataloging, MARC distribution, CONSER, the Canadian Union Catalogue, and shared cataloging.
A computer-generated newspaper index implemented at Iowa State University to replace a card file system is described. The mechanized system employs an algorithmic indexing approach which facilitates data input procedures. The indexer is required to directly select natural-language terms or phrases appearing in the headline or text of the newspaper article as subject descriptors. A comparison with the former card file system indicates that the computer-produced index is cost competitive and provides a more effective retrieval system.
High levels of inflation and drastic cuts in library budgets demand careful planning and effective management control in all aspects of library operations. New and existing library systems must use all resource efficiently particularly staff. This paper deals with existing systems and with improvements in their cost-effectiveness. For example, by adapting the organization and procedures to make more efficient use of existing resources and technology, the cataloging department's productivity and the quality of catalogs can be improved. It will be shown how small changes to an existing computer-based catalog support system can facilitate an entirely new approach to catalog control.
