Under severe library finances, it is very important to get accurate data on the utilization frequency of each periodical. Utilization consists of lending, reading, photocopy and interlibrary loan. For library management and business, this information is as indispensable as citation analysis on Impact Factor and 2-Step Model. This report explains an outline of a survey on the optical character reader system of LICSU-UX (NEC) at Medical Library of Fukuoka University since April 1995. Also this introduces activities based on the results. These activities are, for example, display of newly-arrived periodicals, bookbinding, selection of electronic journal, choice of delivery system, making a list of discontinuance of subscription and other things. And this report proposes to start a survey of utilization throughout libraries of Japan Medical Library Association, to establish a market of recycling of disused periodicals, and to introduce an information retrieval system through the campus local area network in its early stage.
