In a continuing effort to reduce costs and improve internal processes, the Glendale Public Library's book charging and overdue determination system has been examined and an improved method conceived which will free badly needed labor hours within the library. It is proposed that the present photocharging transaction card system be kept, but the handling of transaction cards for the generation of overdue lists be changed from the manual McBee keysort system to a computer processed punched card system. In addition, it is suggested that the date due and overdue system be changed from a daily to a weekly system, which will reduce the clerical load, reduce the computer printout load, and allow more local flexibility in performing staff work. The cost difference between the present and proposed systems is not realizable in dollar savings, but rather in terms of circulation personnel labor that would be freed for other work presently being neglected.
