    Abstract
    Betrachtet werden die drei Fragestellungen: (1) Welche Funktionen erfüllen Schlagwortketten im konventionellen Zettel- oder Listenkatalog? (2) Lassen sich diese Funktionen auf Online-Kataloge übertragen bzw. durch online-typische Funktionen ersetzen? (3) Welche Funktionen können SW-Ketten im Online-Katalog übernehmen?

    Abstract
    Beschäftigt man sich mit Inhaltserschließung, so sind zunächst zwei Dimensionen zu unterscheiden - die Wissensorganisationssysteme selbst (z. B. Normdateien, Thesauri, Schlagwortsprachen, Klassifikationen und Ontologien) und die Metadaten für Dokumente, die mit diesen Wissensorganisationssystemen erschlossen sind. Beides steht in einer Wechselwirkung zueinander: Die Wissensorganisationssysteme sind die Werkzeuge für die Erschließungsarbeit und bilden die Grundlage für die Erstellung konkreter Erschließungsmetadaten. Die praktische Anwendung der Wissensorganisationssysteme in der Erschließung wiederum ist die Basis für deren Pflege und Weiterentwicklung. Zugleich haben Wissensorganisationssysteme auch einen Eigenwert unabhängig von den Erschließungsmetadaten für einzelne Dokumente, indem sie bestimmte Bereiche von Welt- oder Fachwissen modellartig abbilden. Will man nun Aussagen über die Qualität von inhaltlicher Erschließung treffen, so genügt es nicht, den Input - also die Wissensorganisationssysteme und die damit generierten Metadaten - zu betrachten. Man muss auch den Output betrachten, also das, was die Recherchewerkzeuge daraus machen und was folglich bei den Nutzer:innen konkret ankommt. Im vorliegenden Beitrag werden Überlegungen zur Qualität von Recherchewerkzeugen in diesem Bereich angestellt - gewissermaßen als Fortsetzung und Vertiefung der dazu im Thesenpapier des Expertenteams RDA-Anwendungsprofil für die verbale Inhaltserschließung (ET RAVI) gegebenen Hinweise. Im Zentrum steht die verbale Erschließung nach den Regeln für die Schlagwortkatalogisierung (RSWK), wie sie sich in Bibliothekskatalogen manifestiert - gleich, ob es sich dabei um herkömmliche Kataloge oder um Resource-Discovery-Systeme (RDS) handelt.

    Anmerkung: Früher wäre es im RSWK-Kontext aufgefallen, dass es sich bei einer Wortschöpfung 'Erschließungsmetadaten' um einen Pleonasmus handelt.

    Abstract
    Im letzten Heft der VÖB-Mitteilungen wurde über die Erstellung eines hie-rarchischen Browse- und Abfrage-Interfaces für die lokale Systematik im Online-Katalog der Bibliothek der Sigmund Freud Privatstiftung, der im Rahmen eines Aleph-Sharing-Lokalsystems an der Verbundzentrale OBVSG betrieben wird, berichtet. Im Hinblick auf die Darstellung der den Titeldatensätzen jeweils zugeordneten Systematikgruppen in der Vollanzeige des OPACs galt damals noch (sinngemäß): Da vonseiten der Bibliothek lediglich die Notationen katalogisiert werden, wird bei der Titel-Vollanzeige mittels einer JavaScript-basierten Umnutzung der Aleph-Funktion "Suchdienste" ein Link auf das hierarchische Interface generiert, um die Bedeutung der jeweiligen Notation im systematischen Kontext zu veranschaulichen. Diese Lösung, die zwar durchaus besser als das kommentarlose Display einzelner "nackter" Notationen war, ist nunmehr obsolet geworden. Ein vor kurzem implementierter, einfacher Automatismus aus der "Werkstatt" der Verbundzentrale bewirkt die Einspielung der Klassennamen bereits im Katalogisierungsprozess und macht so die Anzeige dieser Benennungen im Katalog (OPAC bzw. Bearbeitungs-GUI) möglich.

    Abstract
    Auf dem Hintergrund der aktuellen OPAC-Entwicklung in Deutschland werden im ersten Teil einzelne Aspekte des OPAC-Designs kommentiert. Es wird u.a. auch auf Möglichkeiten einer Standardisierung der Schnittstelle Retrieval-Software / Benutzeroberfläche eingegangen. Die derzeit dominierenden Online-Kataloge sind für eine Massenbenutzung nur bedingt geeignet, da sie in hohem Maße fehlerintolerant sind, eine Analyse nach Suchfeldern verlangen und mit grundsätzlichen Mängeln der Boole'schen Suchlogik behaftet sind. Im zweiten Teil werden werden Alternativen diskutiert, zum einen in Form eines alphabetisch sortierten Online-Katalogs, zum anderen in Form intelligenter bibliographischer Auskunftssysteme, die Ähnlichkeitssuchen bzw. sog. 'Closest-Match-Suchen' gestatten. Hierzu werden verschiedene Konzepte und Vorschläge vorgestellt

    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
    The human natural ability to store and process images and speech provides clues for improving access to online information. The principles underpinning the maps people use in their minds can be applied to maps that can be presented at the user interface to online systems. Traditional classification organizes information into structured hierarchies and simplifies the search problem, but has serious limitations. Discusses the prospects for improving access to online information through the application of dynamic faceted classification. Presents a glimpse into the navigation of n-dimensional information space for future library OPACs using a modified DDC

    Abstract
    A research project in progress at Middlesex Polytechnic is examining the problems of providing adequate subject access from MARC-based cataloguing systems. Various forms of printed index are being evaluated and an experimental OPAC is being designed. The PRECIS RIN file will be tested as a basis for online thesaural control and as a browsing facility
