The work of the Committee on the use of automation in Swedish research libraries has differed from that of a normal study group by virtue of its heavy concentration on the practical aspects of library catalog work, the present status of which is the main theme of this report. The model presented implies total and simultaneous integration of all Swedish research libraries, a national model which to date has no counterpart elsewhere. A key feature of the project is the catalog scheme based on the MARC systems, which ensures the compatibility of the Swedish model with international systems. For purposes of method development, operation of the proposed data processing center and training of the necessary qualified personnel, the Committee recommends that an independent institution for data processing in libraries be set up on the West German model.
