    Abstract
    The growing interest in end user or direct patron access to on-line bibliographic databases is reviewed with references to online catalogues, databases, and CD-ROMs. The literature of end user searching is surveyed with notes on: user training, software search aids, end user services in libraries: characterisation of end user searches; the role of librarians; and CD-ROMs as end user media

    Abstract
    »Sacherschließung - können wir uns die noch leisten?« Angesichts des zunehmend geringeren Gesamtetats, der den Bibliotheken zur Verfügung steht, drängt sich diese Frage nahezu auf. Sacherschließung ist teuer und für das moderne Bibliothekswesen nur dann noch tragbar, wenn der Mitteleinsatz in einem angemessenen Verhältnis zum Ergebnis steht, das sich in der Leistungsfähigkeit des Produkts widerspiegelt. Im deutschsprachigen Raum trägt die SWD wesentlich zu einer effektiveren Sacherschließungsarbeit bei. Ihre Pflege und Weiterentwicklung ist jedoch mit einem enormen Aufwand gekoppelt, der nur mit einer entsprechenden Nutzung der Daten für das thematische Retrieval in den OPACs gerechtfertigt werden kann.

    Abstract
    Reports on 4 experiments conducted at Sheffield University, Department of Information Studies, UK, into cognitive models which illuminate how people learn using electronic media. The experiments dealt with: learning strategies in an unconstrained electronic environment, in a hypertext environment, and in database searching, and matching and mismatching learning styles. Discusses the positive or negative implications for the design of electronic learning materials suggested by these experiments

    Abstract
    Reports on a study of children's intentions, purposes, search terms, strategies, successes and breakdowns in accessing fiction. Data was gathered using naturalistic methods of persistent, intensive observation and questioning with children in several school library media centres in the USA, including 997 OPAC transactions. Analyzes the data and highlights aspects of the broader context of the system which may help in development of mechanisms for electronic access

    Abstract
    Paper presented at the 14th biennal conf. of IATUL, Cambridge, Mass., USA, 8.-12.7.1991: new technologies and information services - evolution or revolution? Ed.: Jay K. Lucker and published by the British Library on behalf of IATUL. The provision of enhanced subject access and access to a wider variety of bibliographic resources for library users have been influenced by technology. This has occured throuigh advances in workstations, storage media, graphics, networks and search engines such as BRS/SEARCH. Presents the results of a study by the Council of Library Resources on online catalogues. Discusses access to the periodical literature, library workstations, the University of Illinois at Urbana-Champaign library's microcomputer workstation, the OKAPI search system for online catalogues and the Scottish Academic Libraries Bibliographic Information Network

    Content
    "Angesichts des Alters (18401952), der Menge (2,3 Millionen Katalogblätter im Quartformat, daher der Name Quartkatalog) und der Schwierigkeit der Vorlagen (über neunzig Prozent handschriftlich) bot es sich für die BSB an, längere Zeit zu prüfen, welches Retrokonversionsverfahren für das geplante Vorhaben am besten geeignet ist unter besonderer Berücksichtigung von Projektdauer, Kosten und unverzichtbarer hoher Qualität der bei der Retrokonversion erstellten Titeldaten. Sorgfältige Vorarbeiten hatten ein Verhältnis von 65 Prozent Zutragungen zu vorhandenen BVB Titeldatensätzen und 35 Prozent Neuaufnahmen prognostiziert. Als entscheidend für den Konversionserfolg wurde daher eine sehr hohe Genauigkeit bei der Entscheidung Neuaufnahme/ Zutragung angesehen, eine hohe Nachvollziehbarkeit der Rechercheentscheidungen sowie die Vermeidung von Dubletten in der Verbunddatenbank. Vor diesem Hintergrund fiel die Entscheidung zu einem Retrokonversionsverfahren unter Ausspeicherung der vorhandenen BVB-Daten, darunter die von der Deutschen Bücherei Leipzig und der Staatsbibliothek Preußischer Kulturbesitz übernommenen Altdaten, mit besonderem Fokus auf die Qualitätssicherung durch den auszuwählenden Dienstleister. In einer europaweiten Ausschreibung wurde im Oktober 2002 der Anbieter Satz-Rechen-Zentrum (SRZ Berlin) ausgewählt, der in den Jahren 1996-1997 bereits die Retrokonversion des IFK der BSB (2,2 Millionen Karten im internationalen Format) erfolgreich bewältigt hatte. Von Dezember 2002 bis Juli 2003 wurden die Katalogschränke sukzessive nach Berlin transportiert, um an zwei für diesen Zweck speziell gebauten Durchzugsscannern 2,3 Millionen Quartblätter mit Vorder- und Rückseite in 256 Graustufen zu digitalisieren. Die insgesamt 4,6 Millionen Bilder (images) umfassen ein Datenvolumen von 221 GByte."
