    Abstract
    The Chinese Science Citation Database (CSCD) is a significant document database on mainland China, which has been built up by the Documentation and Information Centre of the Chinese Academy of Sciences. Briefly introduces the background to CSCD, and discusses in detail its development and application, source journals and citation data, data processing methods, subject scope, compilation regulations, stylistic rules and layout, and usage directions for both the printed and CD-ROM editions of CSCD which have been published from the data

    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
    Reports recent experiences with the publishing, via the Internet and WWW of ISI's biweekly newspaper, The Scientist; which was originally mounted on the NSFnet. Compares the use of the Internet for SDI by comparing Web searches via AltaVista with similar searches on CD-ROM. Predicts that future current awareness services and SDI services will be linked to electronic periodicals in electronic libraries. Concludes with a note on cited reference searching, a variation on the theme of hypertext searching, with particular reference to SCI and Web crawlers

    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
    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

    "Mikhail Simkin und Vwani Roychowdhury von der University of Califomia, Los Angeles, haben eine in der wissenschaftlichen Gemeinschaft verbreitete Unsitte erstmals quantitativ erfasst. Die Wissenschaftler analysierten die Verbreitung von Druckfehlern in den Literaturlisten wissenschaftlicher Arbeiten (www.arxiv.org/abs/cond-mat/0212043). 78 Prozent aller zitierten Aufsätze - so schätzen die Forscher - haben die zitierenden Wissenschaftler demnach nicht gelesen, sondern nur per 'cut and paste' von einer Vorlage in ihre eigene Literaturliste übernommen. Das könne man beispielsweise abschätzen aus der Analyse fehlerhafter Seitenangaben in der Literaturliste eines 1973 veröffentlichten Aufsatzes über die Struktur zweidimensionaler Kristalle: Dieser Aufsatz ist rund 4300 mal zitiert worden. In 196 Fällen enthalten die Zitate jedoch Fehler in der Jahreszahl, dem Band der Zeitschrift oder der Seitenzahl, die als Indikatoren für cut and paste genommen werden können, denn man kann, obwohl es Milliarden Möglichkeiten gibt, nur 45 verschiedene Arten von Druckfehlern unterscheiden. In erster Näherung ergibt sich eine Obergrenze für die Zahl der `echten Leser' daher aus der Zahl der unterscheidbaren Druckfehler (45) geteilt durch die Gesamtzahl der Publikationen mit Druckfehler (196), das macht etwa 22 Prozent."
