    Abstract
    Google und Konsorten haben das Suchverhalten unserer Nutzer grundlegend verändert. Erwartet wird eine Suche, die einfach, unkompliziert und übersichtlich sein soll. Längst haben Bibliotheken und Anbieter von Bibliothekssystemen darauf reagiert und die Suchoberflächen entschlackt. Trotzdem sehen viele Bibliothekskataloge nach wie vor wie "Bibliothekskataloge" aus. Letztlich versuchen viele der Suchmasken immer noch die Vielfalt der erfassten Metadaten und die daraus resultierenden differenzierten Suchmöglichkeiten den Nutzern auf den ersten Blick nahe zu bringen. Das geht, was zahlreiche Studien belegen, häufig an den Bedürfnissen der Nutzer vorbei: Diese wünschen sich einen einfachen und schnellen Zugriff auf die für sie relevante Information. Bibliothekskataloge sind längst nicht mehr nur Bestandsverzeichnisse, sondern Zugangssysteme zur Vielfalt der von der Bibliothek vermittelten Informationen. Auch hier bieten Systemhäuser inzwischen Lösungen an, bei denen im Sinn einer verteilten Suche weitere Quellen mit einbezogen werden können. Im Folgenden soll der Lösungsweg vorgestellt werden, den die Bibliothek des Wissenschaftsparks Albert Einstein in Zusammenarbeit mit dem Kooperativen Bibliotheksverbund Berlin-Brandenburg (KOBV) eingeschlagen hat, um mit diesen beiden veränderten Grundvoraussetzungen für ihr Serviceangebot umzugehen. Die Bibliothek des Wissenschaftsparks Albert Einstein - eine gemeinsame Bibliothek des GeoForschungsZentrums Potsdam, der Forschungsstelle Potsdam des Alfred Wegener Instituts für Polar- und Meeresforschung (zwei Helmholtz-Zentren) und des Potsdam-Instituts für Klimafolgenforschung (ein Leibniz-Institut) - ist eine Spezialbibliothek mit dem thematischen Schwerpunkt Geowissenschaften auf dem größten Campus der außeruniversitären Forschung in Brandenburg, dem Wissenschaftspark Albert Einstein auf dem Telegrafenberg in Potsdam.
    Der KOBV setzt bereits seit 2005 Suchmaschinentechnologie in verschiedenen Entwicklungsprojekten erfolgreich ein. Zusammen mit der Bibliothek des Wissenschaftsparks Albert Einstein wurde nun der Prototyp einer "Bibliothekssuchmaschine" auf Basis erprobter Open-Source-Technologien aus dem Java-Umfeld (wie Tomcat, Jakarta-Commons, Log4J usw.) als web-basierte Anwendung realisiert, deren Suchmaschinenkern auf der ebenfalls als freie Open-Source Java-Variante erhältlichen Search-Engine-Library Lucene4 basiert. Die erste Version der Bibliothekssuchmaschine läuft seit Ende Oktober im Echtbetrieb. Ziel des Pilotprojektes war die Konzeptionierung, Spezifikation und Implementierung einer neuen, benutzerfreundlichen Suchoberfläche zum schnellen Auffinden fachwissenschaftlich relevanter Daten und Informationen, sowohl in bibliothekseigenen Beständen als auch in zusätzlichen Quellen. Vor dem spezifischen Hintergrund der Spezialbibliothek werden dabei nicht nur Kataloginhalte google-like findbar gemacht, sondern der Suchraum "Katalog" um weitere für die Informationsvermittlung auf dem Campus relevante und spezifische fachwissenschaftliche Inhalte als zusätzliche Suchräume erschlossen. Die neue Anwendung dient dem schnellen Ersteinstieg und leitet die Nutzer dann an die jeweiligen Quellen weiter.

    Abstract
    Conceptual considerations on possible synergies between hypertext and indexing languages' research. The existence of a common conceptual and theoretical background encourages and facilitates cooperation. It is concluded that the conjunction of the almost biological flexibility of the hypertext and the logical and conceptual consistency of indexing languages is a promise of better and more effective information management systems in the future

    Abstract
    Presents a state of the art review of the application oh hypertext searching techniques to online catalogues. The technique improves traditional online catalogues: when consulting the catalogue in a non linear way; and when browsing bibliographic information. New research could improve access to larger databases including thesauri and classification schemes

    Abstract
    Outlines the progress of HyperLib, research which began in 1993 to develop a hypertext interface to the online catalogue and other databases at the University of Antwerp. A human factors oriented design methodology was adopted. A user survey was carried out. The project has focused on development of electronic guides and manual and interfaces to access an academic bibliography database and the UDC subject classification scheme. Evaluation is being carried out in 1995

    Abstract
    The Hyperlib project, which is a joint, EC-funded project, between the libraries of Antwerp and Loughborough universities, aims to investigate the opportunities for a hypertext-structured catalogue at Antwerp University. Essential to the project was a survey of user requirements. Because of time constraints, however, it proved impossible to develop a full hypertext-structured database. As a result of the project a redesigned OPAC will be implemented in Spring 95, which will include individual journal article sand the opportunity to create personalised menu-structures

    Abstract
    We have recently completed a survey of the operational use of hypertext-based information systems in academic, public and special libraries in the UK. A literatur search, questionnaire and both telephone and face-to-face interviews demonstrate that the principle application of hypertext systems is for the implementation of public-access point-of-information systems, which provide guidance to the users of local information resources. In this paper, we describe the principle issuse relating to the design and usage of these systems that were raised in the interviews and that we experienced when using the systems for ourselves. We then present a set of technical recommendations with the intention of helping the developers of future systems, with special attention being given to the need to develop effective methods for system evaluation

    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.

    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
    The development of networked access to academic library catalogue records has been conspicuously slow compared with that of campus wide information systems in general. In cooperation with its systems suppliers BLCMO, the Pilkington Library, Loughborough, UK, is seeking to remedy this situation by developing an interface that allows users to access its OPAC via the W3. The benefits of such a facility are reflected in BLCMP's decision to incorporate a revised version in the forthcoming release of the commercial Talis system; but problems relating to the 'statelessness' of hypertext tranfer protocol (HTTP) and to the inadequacy of traditional catalogue records as access points for electronic information resources are still causes for consideration

    Abstract
    Current online catalogs have problems providing reasonable subject access, often resulting in searches with too few or too many hits. These problems can be improved by enhancing MARC records, building semantic networks through cross-references, and linking subject headings to classification numbers. This paper describes a pilot project to design a hypertext search engine using these principles

    Abstract
    In June 1998 Oakland University's library migrated to a new online catalog. In order to determine user acceptance of the new OPAC, students receiving library instruction were asked to complete an open-ended questionnaire eliciting comments on their likes, dislikes and online catalog preference. From the data collected, a second questionnaire was designed and distributed that focused on specific features of the new catalog identified in the first survey. Results indicated that users overwhelmingly preferred the new OPAC and found it easy to use; however, they experienced some difficulty using special features like truncation. The most popular feature of the new catalog was its remote access capability. Second-generation OPACs possess features - such as electronic reserves capabilities and hypertext links - that are beginning to simplify the search process; but they have not yet developed into the intuitive, comprehensive systems that can empower users to seek information in new ways.
