    Abstract
    In einer früheren Studie wurde bereits der 'informationelle Mehrwert' von bibliographischen Datenbanken durch bibliometrische Nutzung untersucht. Im folgenden soll nun eine visuelle Oberfläche vorgestellt werden, die mit Hilfe einer bibliometrischen 'Sekundärdatenbank' einerseits die Nutzungsmöglichkeiten der zugrundeliegenden bibliographischen Datenbanken vor allem in den Bereichen Wissenschaftsinformation, Forschungsevaluation und Wissenschaftspolitik erweitern soll, andererseits aber auch eine Rückkopplung zu den Aufgaben des traditionellen Retrievals erlaubt. Die visuelle Oberfläche 'Visual Bibliometrics' ist eine Erweiterung des CD-Edition des 'Science Citation Index' und des 'Social Science Citation Index'

    Abstract
    'Zwischenruf' zur Zitierpraxis im Wissenschaftsbereich: "Jeder kann seine Plazierung auf dieser Weltrangliste gelehrter Eitelkeit verbessern, indem er sich so oft und andere so wenig wie möglich zitiert. Die Verbreitung des Ruhms, den man braucht, nimmt man am besten selbst in die Hand, von Jugend an"

    Abstract
    Ein überfordertes Gutachter-System, knapper fließende Forschungsgelder sowie die starke Faszination von Ranglisten bewirken zunehmend den Einsatz bibliometrischer Methoden zur Messung von Forschungsqualität. Grundlage der meisten Bewertungen ist der Science Citation Index, der nun auch in der Version als Online-Datenbank für umfangreiche Analysen genutzt werden kann. Erweiterungen der Retrievalsprache beim Host STN International ermöglichen statistische Analysen, die bisher nur dem SCI-Hersteller und wenigen Spezialisten vorbehalten waren. Voraussetzung für eine sinnvolle Anwendung sind vor allem die Wahl geeigneter Selektionskriterien sowie die sorgfältige Interpretation der Ergebnisse im Rahmen der Grenzen dieser Methoden

    Abstract
    Das ISI in Philadelphia bündelt seine großen Zitationsdatenbanken und bietet sie (vorzugsweise als Intranet-, aber auch als Internetlösung) als 'Web of Science'an. Im derzeitigen entwicklungsstand geht 'Web of Science' bis in die 70er Jahre zurück und weist damit knapp 20 Mill. Quellenartikel mit darin enthaltenen rund 300 Mill. Zitationen in einer einzigen datenbank nach. Neben 'gewohnten' Suchstrategien etwa nach Sachthemen oder Namen werden zitationsanalytische Suchstrategien geboten: Recherchen nach zitierter Literatur, nach zitierenden Artikeln und nach (im Sinne gemeinsamer Fußnoten) 'verwandten' Artikeln. Die Ausgabefunktionen umfassen Document Delivery via ISI sowie Links zu Artikeln, die parallel zur Druckausgabe im WWW erscheinen. Durch die Multidisziplinarität der ISI-Datenbanken sind als Kundenkreis vor allem Einrichtungen angesprochen, die mehrere Wissenschaftsfächer berühren. Hochschulbibliotheken oder Bibliotheken großer Forschungseinrichtungen dürften am 'Web of Science' kaum vorbeikommen. Parallele Produkte bei Online-Archiven, auf CD-ROM oder als Druckausgabe verlieren an Bedeutung

    Abstract
    Als Maß für die Produktivität und den Einfluß von Forschern, wissenschaftlichen Einrichtungen und Fachbereichen dienen häufig anhand von Publikations- und Zitationsanalysen erstellte Ranglisten. Doch nach welchen Kriterien sind die in elektronischen Fachdatenbanken gespeicherten Informationen auszuwerten, um ein einigermaßen zutreffendes Abbild der Forschungsleistung zu erhalten?

    Abstract
    Literaturdatenbanken wurden eigentlich mit zwei Zielen aufgebaut: einerseits Fachliteratur zu archivieren und zu dokumentieren und andererseits die Literaturhinweise den Wissenschaftlern für Recherchen zur Verfügung zu stellen. Aus diesen gespeicherten Datenmengen kann man baer auch allgemeine Erkenntnisse über die Literatur eines Fachgebietes und das Verhalten der Forscher gewinnen. Vor allem seit den sechziger Jahren, seit dem Aufbau des Science Citation Index - in dem man auch nach zitierten Arbeiten suchen kann - gibt es eine Fülle von informationswisenschaftlichen und wissenssoziologischen Untersuchungen mit Datenbanken

    Abstract
    Sinnvolle forschungspolitische bzw. forschungsstrategische Entscheidungsprozesse bedürfen beim Wissenschafts- und Forschungsmanagement ausreichender Informationen hinsichtlich der Forschungsaktivitäten bestimmter Wissenschaftlergruppen, Institutionen bzw. Länder. Durch entsprechende Vergleichsuntersuchungen lassen sich u.a. auch thematische, länderweite bzw. zeitkritische Forschungsschwerpunkte herausarbeiten. Die folgende Arbeit skizziert die Möglichkeiten von Forschungsanalysen mittels Online-Datenbanken und verdeutlicht die spezifischen Möglichekeiten und Probleme am Beispiel von Arbeiten aus der Festkörperphysik

    Abstract
    There is an ongoing discussion on the influence of international collaboration on impact as measured by citation based indicators. Collaboration generally involves more authors than 'no collaboration' work and it is obvious that the phenomenon of self citation will be stronger (there are more authors to cite themselves). Thus it can be seen as an important 'amplifier' of measured impact. Asserts, however, that this effect should not be considered as the only or even major explanation of higher impact in the comparison between 'no collaboration' and international collaboration. Using data of an extensive bibliometric study of astronomical research in the Netherlands, proves that higher rates of self citation in international collaboration do not play any significant role as 'impact amplifier'. The central point is that proper impact measurement must involve corrections for self citations

    Abstract
    In this article a quantitative study is reported on the resistance that scientists may encounter when they do innovative work or when they attempt to publish articles that later become highly cited. A set of 205 commentaries by authors of some of the most-cited papers of all times have been examined in order to identify those articles whose authors encountered difficulty in getting his or her work published. There are 22 commentaries (10,7%) in which authors mention some difficulty or resistance in doing or publishing the research reported in the article. Three of the articles which had problems in being published are the most cited from their respective journals. According the authors' commentaries, although sometimes referees' negative evaluations can help improve the articles, in other instances referees and editors wrongly rejected the highly cited articles
