Data analysis of a questionnaire completed by 38 public libraries in the United States and Canada who possess "turnkey" automated circulation systems is presented. Results show that libraries are enthusiastic about benefits to staff and patrons. For libraries with increasing circulation, the computer allows more time to handle additional work load without hiring more staff. For libraries with little growth, an automated system allows them to reduce the number of people at the circulation desk and to assign them to less routine tasks. Library usage insights were gained. Minor breakdowns and software problems were generally tolerated, but major problems and user inconvenience were less tolerated. Conversion of bibliographic data into machine readable format created a large task which libraries dealt with by hiring part-time personnel. The majority agreed that they would automate if they had the chance to do it over--benefits are evident once the system is operational. Satisfaction with vendor support was expressed. A significant number reported power failures due to voltage variations on power lines--most have had voltage regulators installed. Appendices include lists of libraries that responded and vendors of automated circulation control systems, as well as the survey questionnaire. (Author/MBR)
