    Abstract
    In den USA haben schon eine ganze Reihe von Bibliotheken ihre Zettelkataloge geschlossen und durch den Online Public Access Catalogue (OPAC) ersetzt. Der Verbund der Bibliotheken der obersten Bundesbehörden hat den Versuch geagt, diese Form der Katalogbenutzung auch in das deutsche wissenschaftliche Bibliothekswesen einzuführen. Das hessische Bibliotheksinformationssystem HEBIS wurde in diesem Sinne weiterentwicklet. Die Ausprägungen dieses deutschn OPAC werden im folgenden beschrieben

    Abstract
    In Northern Germany, the State of Lower Saxony has developed an online library network, the center of which is the Library Computer Center at the State and University Library in Goettingen. This center offers the following data bases online: the union catalogue of serials in Lower Saxony libraries; the union catalogue of books since 1977 in these libraries; the IBZ and IBR; the last two years of the Deutsche Bibliographie, the British National Bibliography and, within the next few months, the titles offered by the Library of Congress (all in full service); then all new titles in this data base will be compatible to MARC II.

    Abstract
    The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.
