    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.

    Abstract
    This article discusses the major catalog use studies that have been conducted in the United States and Great Britain. The potential to influence the construction of new online public access catalogs is emphasized. The cumulative findings could serve as an information base which designers of OPAC systems could refer to in the course of their work

    Abstract
    Discusses the necessity of providing new methods of research into user information retrieval behaviour. Notes that the user using the catalogue via the Internet and communicating exclusively with the computer system, disappears from the librarian's direct view. Implementing adequate software facilities in some sense broadens research prospects and improves its quality. Describes research carried out at the Jagiellonian Library, Poland, into the extent of use of OPAC retrieval facilities, throught the application of software that records all information retrieval commands

    Abstract
    Vom verflixten siebten Jahr kann man in Bregenz bisher nicht sprechen, im Gegenteil: Die Vorarlberger Landesbibliothek (VLB) hat kurz vor Ostern 2008 ihr 100.000. Inhaltsverzeichnis mit intelligentCAPTURE gescannt. Damit ist der Katalogeintrag von etwa 70 Prozent des betroffenen Freihandbestandes und sämtlicher Neuzugänge ab 2002 zusätzlich mit dem Inhaltsverzeichnis und zum Teil mit der Abbildung des Buchdeckels versehen. Die derzeitige Durchsatzrate beträgt pro Jahr 30.000 bibliographische Einheiten bei einem Personaleinsatz von 40 Stunden pro Woche. Die vollständige Erschließung des Buchbestandes in der Freihandaufstellung ist in Reichweite; ganz ohne Fördermittel im laufenden Betrieb; eine schlanke Lösung sowohl organisatorisch als auch finanziell. Da im Rahmen der Zusammenarbeit mit dandelon.com inzwischen weitere Bibliotheken in einem elegant gelösten Arbeitsablauf kooperativ erschließen, können wir bei Neuerscheinungen bereits die Hälfte als Fremddaten übernehmen. Die VLB hat mit der Digitalisierung, OCR-Konvertierung und maschinellen Indexierung von Inhaltsverzeichnissen und dem mehrsprachigen, semantischen Retrieval in der Suchmaschine dandelon.com zusammen mit der Firma AGI. Information Management Consultants Impulse im Bibliothekswesen gesetzt. Wer 2002 noch bezweifelte, dass dieser Ansatz erfolgreich sein wurde, wurde inzwischen eines Besseren belehrt. Zu offensichtlich ist der Mehrwert, den allein die Moglichkeit der entscheidend verbesserten Relevanzbeurteilung uber den OPAC bietet (http://vlb-katalog.vorarlberg.de). Er erfordert von einer zeitgemasen Bibliothek geradezu das Angebot solcher Zusatzinformationen. Aber die Anreicherung mit den Angaben aus den Inhaltsverzeichnissen bieten weit mehr, denn es entsteht durch die maschinelle Indexierung eine vollig neue Dimension an Retrievalmoglichkeiten. Die vollständige Erfassung unseres Bestandes war immer erklärtes Ziel unseres Projektes, weil wir gesehen haben, dass wir den Nutzern dadurch einen erheblichen Zusatznutzen bieten können, der in einem unbeschreiblich günstigen Verhältnis zum personellen und finanziellen Einsatz steht. Damit, dass wir dieses Ziel so schnell erreichen könnten, hatten wir nicht gerechnet.

    Abstract
    Current online catalogs have problems providing reasonable subject access, often resulting in searches with too few or too many hits. These problems can be improved by enhancing MARC records, building semantic networks through cross-references, and linking subject headings to classification numbers. This paper describes a pilot project to design a hypertext search engine using these principles

    Abstract
    Reports from a study investigating the extent to which academic end users conduct multiple search sessions, over time woth OPAC or CD-ROM databases at different stages of their information seeking related to a current research project. Interviews were conducted using a questionnaire with 200 academic end users at Rutgers University Alexander Library, NJ and University of North Texas, to investigate the occurrence of multiple search sessions. Results show that at the time of the survey interview, 57% of end users had conducted multiple search sessions during their research project and 86% of end users conducted their 1st search session at the beginning stage of their information seeking process. 49% of end users had conducted between 1 and 6 search sessions and 8% more than 6 search sessions. 70% of multiple search sessionss end users had modified their search terms since their 1st search session. Discusses the implications of the findings for end user training, information retrieval systems design and further research

    Abstract
    A project to design a graphical user interface for the OKAPI online catalogue search system which uses the basic term weighting probabilistic search engine. Presents a research context of the project with a discussion of interface and functionality issues relating to the design of OPACs. Describes the design methodology and evaluation methodology. Presents the preliminary results of the field trial evaluation. Considers problems encountered in the field trial and discusses contributory factors to the effectiveness of interactive query expansion. Highlights the tension between usability and functionality in highly interactive retrieval and suggests further areas of research

    Abstract
    Reports an empirical study at the Queriniana Civic Library, Brescia, of interaction betwee researchers and printed catalogues during bibliographic data retrieval. The study sought to ascertain frequency of catalogue use; research success rate and time taken; and to identify user profiles. Data were obtained by a mixture of questionnaires, interviews and direct observation. Findings showed that 64% of the catalogue users were female; 70% were aged 19-30; 65% were university students or had good school grades; and hardly any were working class. University students preferred keyword access. 50% or all searches were successful. Most search failures related to subject catalogues, which usually required more time. Provides statistics on time spent in research

    Abstract
    Purpose - The purpose of this paper is to investigate the usability of a web-based OPAC (WebPAC) user interface at the International Islamic University Malaysia (IIUM). It also looks at the applicability of heuristic evaluation in designing a user-centered WebPAC interface. Design/methodology/approach - Based on Nielsen's ten usability heuristic principles, the study focuses on three heuristics only, i.e. aesthetic and minimalist design, match between interface and the real world, and visibility of interface status. Findings - Results of the study found that the WebPAC interface conforms to at least 70 percent usability properties prescribed. Usability problems violated in the interface were identified. Practical implications - The study suggests that heuristic evaluation is applicable in libraries to asses the usability of user interface for online catalogs. Originality/value - Heuristic evaluation could assist libraries in designing user-centered interface for online catalogs.
