contents	Clinic on Library Applications of Data Processing, 1972. Proceedings: Applications of On-Line Computers to Library Problems. Lancaster, F. Wilfrid, Ed. Cataloging Computers Conference Reports Data Processing Library Acquisition Library Automation Library Circulation Library Networks Library Technical Processes Online Systems Serials In planning this ninth annual clinic an attempt was made to include papers on a wide range of library applications of on-line computers, as well as to include libraries of various types and various sizes. Two papers deal with on-line circulation control (the Ohio State University system, described by Hugh C. Atkinson, and the Northwestern University system, described by Joseph T. Paulukonis), one with acquisitions (LOLITA at Oregon State University Library, described by Larry Auld and Robert Baker), one with serials control (a system at the Biomedical Library, UCLA, described by James Fayollat) and one with on-line cataloging procedures (used in the Shawnee Mission Public Schools and described by Ellen Miller and B. J. Hodges). Multi-functional on-line systems are represented by the BALLOTS project at Stanford University (described by A. H. Epstein and Allen B. Veaner). I. A. Warheit of IBM gives a comprehensive overview of the application of on-line interactive systems in libraries. Irwin Pizer describes the use of such systems in library networks, and Glyn T. Evans undertakes the difficult task of identifying and summarizing key points made by the speakers. (Author/SJ)
