    Abstract
    One of the most common errors in cataloguing library materials involves miscoding of the nonfiling indicator of title fields. Notes the extent of the problem and its negative effect on searching in the library's online catalogue and surveys how librarians have approached solutions to the problems. Describes how the major library automation system address this problem

    Abstract
    Discusses and illustrates the essential features of user-system interfaces designed to support end user searching. Presents examples of interfaces to support the following basic information seeking functions are presented: problem definition, source selection, problem articulation, examination of results, and information extraction. Argues that present interfaces focus on problem articulation and examination of results functions, and research and development are needed to support the problem definition and information extraction functions

    Abstract
    Das in den letzten Jahren wiedererwachte Interesse an der klassifikatorischen Erschließung und Recherche hat sich allem Anschein nach noch nicht ausreichend bis zu den Herstellern integrierter Bibliothekssysteme herumgesprochen. Wie wäre es sonst zu erklären, dass im OPAC-Modul eines führenden Systems wie Aleph 500 so gut wie keine Features für klassifikationsbasierte Recherchen zu erblicken sind? Tatsächlich finden wir heute einen im Vergleich zum einstigen System Bibos kaum veränderten Zustand vor: Notationen eines oder mehrerer Klassifikationssysteme können in einer durch MAB dafür bestimmten Kategorie (700, nebst Indikatoren) katalogisiert und dann recherchiert bzw. angezeigt werden. Doch welcher Benutzer weiß schon, was diese Notationen im einzelnen bedeuten? Wer macht sich die Mühe, dies selbst herauszufinden, um dann danach zu recherchieren? Hier liegt im wesentlich dasselbe Problem vor, das schon dem systematischen Zettelkatalog anhaftete und ihn zu einem zwar mühevoll erstellten, aber wenig genutzten Rechercheinstrument machte, das nur dann (zwangsläufig) angenommen wurde, wenn ein verbaler Sachkatalog fehlte. Nun könnte eingewandt werden, dass im Vergleich zu früher unter Aleph 500 wenigstens das Aufblättern von Indizes möglich sei, sodass im OPAC ein Index für die vergebenen Notationen angeboten werden kann (bzw. mehrere solche Indizes bei Verwendung von mehr als nur einem Klassifikationssystem). Gewiss, doch was bringt dem Uneingeweihten das Aufblättern des Notationsindex - außer einer alphabetischen Liste von kryptischen Codes? Weiter könnte man einwenden, dass es im Aleph-500-OPAC die so genannten Suchdienste ("services") gibt, mithilfe derer von bestimmten Elementen einer Vollanzeige hypertextuell weiternavigiert werden kann. Richtig, doch damit kann man bloß wiederum den Index aufblättern oder alle anderen Werke anzeigen lassen, die dieselbe Notationen - also einen Code, dessen Bedeutung meist unbekannt ist - aufweisen. Wie populär mag dieses Feature beim Publikum wohl sein? Ein anderer Einwand wäre der Hinweis auf das inzwischen vom Hersteller angebotene Thesaurus-Modul, das vermutlich auch für Klassifikationssysteme eingesetzt werden könnte. Doch wie viele Bibliotheken unseres Verbundes waren bisher bereit, für dieses Modul, das man eigentlich als Bestandteil des Basissystems erwarten könnte, gesondert zu bezahlen? Schließlich mag man noch einwenden, dass es im Gegensatz zur Bibos-Zeit nun die Möglichkeit gibt, Systematiken und Klassifikationen als Normdateien zu implementieren und diese beim Retrieval für verbale Einstiege in die klassifikatorische Recherche oder zumindest für die Veranschaulichung der Klassenbenennungen in der Vollanzeige zu nutzen. Korrekt - dies ist möglich und wurde sogar einst für die MSC (Mathematics Subject Classification, auch bekannt als "AMS-Klassifikation") versucht. Dieses Projekt, das noch unter der Systemversion 11.5 begonnen wurde, geriet jedoch nach einiger Zeit ins Stocken und fand bedauerlicherweise nie seinen Weg in die folgende Version (14.2). Mag auch zu hoffen sein, dass es unter der neuen Version 16 wieder weitergeführt werden kann, so weist dieses Beispiel doch auf die grundsätzliche Problematik des Normdatei-Ansatzes (zusätzlicher Aufwand, Kontinuität) hin. Zudem lohnt sich die Implementierung einer eigenen Normdatei 4 wohl nur bei einem größeren bzw. komplexen Klassifikationssystem, wogegen man im Falle kleinerer Systematiken kaum daran denken würde.

    Abstract
    Online catalog users search predominately by subject, yet it is the most difficult search to perform and retrieves records only about one-half of the time. A new generation of OPACs (online public access catalogs) is on the horizon, the Web-based OPAC. Web-based OPACs allow users to access online catalogs through a WWW (World Wide Web) interface and have the potential to improve patrons' ability to search by subject. But will this potential be realized? This article proposes some basic guidelines that can be incorporated into Web-based OPAC interface design to help users perform subject searches more effectively, and evaluates how well Web-based OPACs currently in operation address the subject searching problem

    Abstract
    Describes the technical aspects of a feasibility study to test a new concept in bibliographic control based on the manifestations of a work. Conventional catalogues are based on the main entry principle which follows from the concept that there should be 1 main entry for each work. The Bradford OPAC project, at Bradford University, UK, aimed to develop a new type of hierarchical bibliographic record structure to cope with the problem of applying the main entry principle to multiple cataloguing records which are manisfestations of the same work. The project involved the storage of MARC data sets of bibliographic records, taken from the Bradford University Library OPAC and the OCLC WorldCat database, in a relational database (MS Access) on a PC. This was then used for an experimental Windows based OPAC, to evaluate the overall success of the idea and any problem areas identified with a view to a more substantial study. The project also aimed to test whether intelligent and responsive software, using a graphic user interface and based on sets of manifestations, could provide a better route to information than a display based on a single work
