The Medical Sciences Library of the University of California, Irvine acquired an on-line serials control system quickly and at low cost by entering into a consortium with the University of California, Los Angeles Biomedical Library, whose on-line serials system has been in existence and operating successfully for four years. The conversion was funded by the National Library of Medicine grant and was carried out mainly by the existing serials staff. The conversion from a manual to an on-line system caused numerous problems, and though the system is an enormous improvement, there are still minor difficulties. (Author/EMH)
