A comparative analysis is presented of the time and cost to a library of providing on-line searching services without charge or for a fee. When the service was free to the user the cost to the library averaged $26.73, and when a fee was charged the cost was $28.78. Shifts in library resources were found to have taken place, with the librarian spending relatively more time preparatory to and subsequent to the search and less time at the terminal during the pay period than during the free period. Data base connect charges were found to have decreased by $5.75 and off-line print costs to have increased by $2.00 from the free to the pay period. A sharp decrease of 3.4 days (44 percent) occurred between periods in the time required to process a request.
The on-line use of data bases requires the education and training of the users of data bases and on-line services. This paper discusses vehicles for education and training, tools and techniques for promotion, and details the information requirements of the processors, service managers, searchers, and end users.
The North American library community is beginning to plan for the development of a national library network. Before such a network can become a reality, certain problems must be addressed. Wide participation in the building of this network is essential for its success.
In 1976 the Research Libraries Group selected a CRT terminal for use in the initial development of its bibliographic system. This article describes the various terminals examined during the selection process and how they appeared to meet both research library needs and RLG's special requirements. Similar discussion is presented for hard-copy printers to be attached to the CRT terminal.
The Government Publications Section of the University of Toronto Library has recently instituted a new, computer-aided method of document processing. A dual format is being used: a subset of MARC and the Ontario Universities' Library Cooperative System's Cooperative Documents Project format (CODOC). Reasons for opting for CODOC are discussed. A tag-by-tag comparison of the two formats is presented. The study closes with a description of the practical application and products of the system.
