This report covers Phase IIB (1 January 1971 to 30 June 1972) of the development of a campus-based Center for Information Services (CIS) at the University of California at Los Angeles (UCLA). Activities during this phase included completion of the design and programming details of the software system, development of a prototype of the software system, acquisition of selected data bases, development of operational procedures, operation of experimental current awareness search services with interim software, seminars for library personnel, and the establishment of procedures for the transfer of the operation to the library. Two highlights of the phase were the outstanding success of the experimental current awareness service and the establishment of a CIS unit in the library. (Author)
