- SDI Citation Checking as a Measure of the Performance of Library Document Delivery Systems. Bourne, Charles P. Robinson, Jo. Citations (References) College Libraries Information Services Library Collections Library Services Research Needs Selective Dissemination of Information Document delivery support for selective dissemination of information (SDI) services provided by the Center for Information Services, University of California at Los Angeles, was measured by the following: (1) Obtaining copies of all steady-state SDI searches from Biological Abstracts'"BA Previews" data base delivered to the University of California at Berkeley campus; (2) Determining potential availability of the citations by look-up in the University of California at Berkeley library catalogs; and (3) Determining actual availability by placing hands on the cited publications. Twenty-three SDI printouts containing 680 citations, for thirteen users, were studied, 6 0/0 of the total citations were found on the shelves. Of the potentially-available citations, 85.4 0/0 were found on the shelves. This methodology is suggested as an unobtrusive measure of the extent to which a library's collection can support its patrons' current research interests in a variety of subject fields. (Author/SJ)
