    Abstract
    Argues that the current understanding of main entry is the chief access point for the work in a physical item being described by a bibliographic record. Explains the justification for main entries while drawing attention to the few related problems as they relate to OPACs

    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
    The Bradford OPAC is an experimental prototype OPAC, with a graphical user interface, based on the manifestation concept. It was designed to study some of the problems in catalogues where there are many versions of the same work or complex multipart works. In place of the main entry based approach of one complete record for each item, the OPAC groups together into sets items that are manifestations of the same work. Users are presented with shorter lists of different intellectual works. Items in a set can be sorted, searched and displayed according to user supplied criteria

    Abstract
    In this article, we examine some of the proposals which have dealt with the problems in cataloging in 2 different technological contexts: printed-card catalogs and online catalogs. We first look at some of the measures which attempted to deal with the 'crisis in cataloging' at the Library of Congress in the 1940s. Then we address some of the current problems in cataloging in the era of OPACs. In particular, we discuss the extent to which minimal-level cataloging, as defines by AACR and implemented in the OCLC database, works for maps. Our discussion is organized around 2 main groups of access points: controlled vocabulary data elements, including name data elements, and free-text data elements. In closing, we discuss prospects that the next generation of online catalogs uisng the Z39.50 protocol and SGML format might offer to minimal-level cataloging for maps

    Content
    Die Deutsche Bibliothek Retrieval von Content In dem Projekt wird angestrebt, Verfahren zu entwickeln und einzuführen, die automatisch und ohne intellektuelle Bearbeitung für das Content-Retrieval ausreichend Sucheinstiege bieten. Dabei kann es sich um die Suche nach Inhalten von Volltexten, digitalen Abbildern, Audiofiles, Videofiles etc. von in Der Deutschen Bibliothek archivierten digitalen Ressourcen oder digitalen Surrogaten archivierter analoger Ressourcen (z. B. OCR-Ergebnisse) handeln. Inhalte, die in elektronischer Form vorhanden sind, aber dem InternetBenutzer Der Deutschen Bibliothek bisher nicht oder nur eingeschränkt zur Verfügung stehen, sollen in möglichst großem Umfang und mit möglichst großem Komfort nutzbar gemacht werden. Darüber hinaus sollen Inhalte benutzt werden, die für ein in ILTIS katalogisiertes Objekt beschreibenden Charakter haben, um auf das beschriebene Objekt zu verweisen. Die höchste Priorität liegt dabei auf der Erschließung von Inhalten in Textformaten. In einem ersten Schritt wurde der Volltext aller Zeitschriften, die im Projekt "Exilpresse digital" digitalisiert wurden, für eine erweiterte Suche genutzt. In einem nächsten Schritt soll die PSI-Software für die Volltextindexierung von Abstracts evaluiert werden. MILOS Mit dem Einsatz von MILOS eröffnet sich die Möglichkeit, nicht oder wenig sachlich erschlossene Bestände automatisch mit ergänzenden Inhaltserschließungsinformationen zu versehen, der Schwerpunkt liegt dabei auf der Freitext-Indexierung. Das bereits in einigen Bibliotheken eingesetzte System, das inzwischen von Der Deutschen Bibliothek für Deutschland lizenziert wurde, wurde in eine UNIX-Version überführt und angepasst. Inzwischen wurde nahezu der gesamte Bestand rückwirkend behandelt, die Daten werden im Gesamt-OPAC für die Recherche zur Verfügung stehen. Die in einer XMLStruktur abgelegten Indexeinträge werden dabei vollständig indexiert und zugänglich gemacht. Ein weiterer Entwicklungsschritt wird in dem Einsatz von MILOS im Online-Verfahren liegen.
