In 1961 the University of California at San Diego library began design of a computerized serials system with 700 entries. From this a sophisticated system has evolved (through three computers) with 30,810 serial entries in 1973. Using batch processing, the computer generates copies of a union list of university serials holdings, copies of serials lists for each of the branch libraries, and an expected arrivals list used for checking in newly received issues, for which cards are punched for input into the master file. Lists of volumes to be bound are also generated, and information on missing issues and claims can be obtained. Examples of printout information are shown, and the appendixes include systems flow charts, processing and operating instructions, and systems programs. (LS)
