    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.

    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

    Abstract
    Attempts to gauge whether syndetic structure, the cross reference system long regarded as an integral component of the controlled vocabulary which predominates as the indexing framework for online subject searching, still has a role to play in assisting end users in their information quests. To this end, examines a number of existing and proposed enhancements to OPACs by means of a literatur review. These include: Boolean and keyword searching; online browsing; artificial intelligence; classification clustering; and hypertext. Discusses Dervin's sensemaking theories and methodologies

    Abstract
    Introducess a new approach to display retrieved subject headings in subject searching designed to encourage users to browse bibliographic information. Emphasizes the importance of the exact display approach by showing how many user queries could be candidates for this approach, demonstrates an implementation of the exact-display approach in an experimental online catalogue. End user experiences gives opportunities to make recommendations for enhancing the original design of the exact display approach so that future implementations of this approach in operational online catalogues are responsive to the needs of online catalogue users

    Abstract
    The construction and updating of indexing languages depend on the organization of their hierarchical structures in order to determine the classification of related terms and, above all, to allow a constant updating of vocabulary, a condition for knowledge evolution. The elaboration of an indexing language for online catalogs of libraries' networks is important considering the diversity and specificity of knowledge areas. From this perspective, the present paper reports on the work of a team of catalogers and researchers engaged in the construction of a hierarchical structure of an indexing language for an online catalog of a university library's network. The work on hierarchical structures began by defining the categories and subcategories that form the indexing language macrostructure by using the parameters of the Library of Congress Subject Headings , the National Library Terminology and the Vocabulary of the University of São Paulo Library's system. Throughout the stages of the elaboration process of the macrostructure, difficulties and improvements were observed and discussed. The results enabled the assessment of the hierarchical structures of the languages used in the organization of the superordinate and subordinate terms, which has contributed to the systematization of operational procedures contained in an indexing language manual for online catalogs of libraries.

    Abstract
    Browse searching of online catalogs and electronic indexes is a popular means of retrieving information, but some subject heading lists are so extensive that browsing them can be difficult and time-consuming. This resaerch tested one way of presenting a browse interface to reduce the amount of scanning of subject headings required. It found that a hierarchical presentation of headings reduced the amount of scanning required by more than 50% without any reduction in the effectiveness of the search. Better browsable displays of this sort can improve the efficiency of searching but appear not to alter effectivenenss

    Abstract
    Purpose - This paper aims at providing a robust, user-friendly and efficient navigation procedure in an online library catalog that is based on semantic information encapsulated within subject headings. Design/methodology/approach - The paper describes an interactive navigation procedure inside an online library catalog based on semantic information. The proposed approach is presented through a web-based, prototype application following the most recent trends of the semantic web such as AJAX technology and the web ontology language - OWL for encoding semantics. Findings - According to the proposed method, a GUI interface exposes the hierarchy of the subject headings employed within an OPAC, as well as all stated relations between such headings, as links that the user can follow, effectively traversing the ontology and formulating at the same time the actual query to the underlying OPAC. This act of interactive navigation through the library's assets aids searchers in accurately formulating their queries, by offering broader or narrower concepts for selection or indicating alternative or related concepts they might be initially unaware of. The augmented exposition of inter-relations between concepts provides multiple paths for information retrieval and enables searchers to fulfill their information needs in a faster, more efficient and intuitive manner. Practical implications - The paper includes implications for the development of modern, semantic web applications focused on the library domain. The novel approach of visualizing subject headings could be further extended to visualize a number of other conceptualizations of the library domain. Originality/value - This paper fulfils an identified need to take advantage of the "hidden knowledge" existing within the library domain but, for a number of reasons, is never exposed to the library users.
