    Abstract
    Die Webometrie ist ein Teilbereich der Informationswissenschaft der zur Zeit auf die Analyse von Linkstrukturen konzentriert ist. Er ist stark von der Zitationsanalyse geprägt, wie der empirische Schwerpunkt auf der Wissenschaftsanalyse zeigt. In diesem Beitrag diskutieren wir die Nutzung linkbasierter Maße in einem breiten informetrischen Kontext und bewerten verschiedene Verfahren, auch im Hinblick auf ihr generelles Potentialfür die Sozialwissenschaften. Dabei wird auch ein allgemeiner Rahmenfür Linkanalysen mit den erforderlichen Arbeitsschritten vorgestellt. Abschließend werden vielversprechende zukünftige Anwendungsfelder der Webometrie benannt, unter besonderer Berücksichtigung der Analyse von Blogs.

    Abstract
    Deutschsprachige Fachzeitschriften des Bibliotheks- und Informationswesens (BID) werden über Kennwerte zur Leserwahrnehmung (Lesehäufigkeit, Anwendbarkeit der gelesenen Inhalte, Publikationshäufigkeit, Publikationspräferenz), Zitatenanalyse (Impact Factor, Halbwertszeit der Referenzen, Referenzen pro Artikel, Anteil der Zeitschriftenselbstreferenzen) und der Redaktion (Struktur der Autoren- und Leserschaft, Artikelauswahl, Ablehnungsquote, Überarbeitungsquote) szientometrisch beschrieben. Besonderes Augenmerk wird auf die Gegenüberstellung der Ergebnisse der Teilstudien gelegt. Die deutschsprachigen BID-Zeitschriften werden von Praktikern als Autoren wie als Leser dominiert. Praktiker schreiben für Praktiker, es wird wenig zitiert, aktuelle Themen überwiegen. Die Ablehnungsquoten eingereichter Artikel sind gering; durchgehendes Peer Review ist bei der Artikelauswahl die Ausnahme. Einige deutschsprachige BID-Zeitschriften (vor allem die Verbandszeitschriften) gleichen informationellen Inseln. Eine informations- und bibliothekswissenschaftliche Zeitschrift, die internationalen Qualitätsstandards folgt und die für das gesamte BID relevante Themen behandelt, fehlt in den deutschsprachigen Ländern völlig.

    Abstract
    In diesem Beitrag wird eine szientometrische Studie zum Informationsmanagement vorgestellt. Unter Verwendung von Science Citation Index und Social Science Citation Index wurde die Literatur zum Informationsmanagement nach verschiedenen Kriterien (Fachgruppen, in denen publiziert wird; Herkunft der Autoren; Publikationssprachen; zeitliche Verteilung) ausgewertet. Darüber hinaus wurde eine Zitatenanalyse durchgeführt. Auf Basis einer Autoren-Kozitationsanalyse wurde schließlich die formale Wissenschaftskommunikation im Bereich des Informationsmanagements abgebildet. Neben den Ergebnissen werden aber auch die Problembereiche aufgezeigt, die mit szientometrischen Untersuchungen verbunden sind

    Abstract
    Collaboration is a major research policy objective, but does it deliver higher quality research? This study uses citation analysis to examine the Web of Science (WoS) Information Science & Library Science subject category (IS&LS) to ascertain whether, in general, more highly cited articles are more highly collaborative than other articles. It consists of two investigations. The first investigation is a longitudinal comparison of the degree and proportion of collaboration in five strata of citation; it found that collaboration in the highest four citation strata (all in the most highly cited 22%) increased in unison over time, whereas collaboration in the lowest citation strata (un-cited articles) remained low and stable. Given that over 40% of the articles were un-cited, it seems important to take into account the differences found between un-cited articles and relatively highly cited articles when investigating collaboration in IS&LS. The second investigation compares collaboration for 35 influential information scientists; it found that their more highly cited articles on average were not more highly collaborative than their less highly cited articles. In summary, although collaborative research is conducive to high citation in general, collaboration has apparently not tended to be essential to the success of current and former elite information scientists.

    Abstract
    Ziel dieses Beitrags ist es, am Beispiel unserer eigenen Disziplin Möglichkeiten zur Recherche nach elektronischen Zeitschriften (EJournals) vorzustellen und zu bewerten. Vorweg drei definitorische Festlegungen: EJournals meint hier via WWW verfügbare Zeitschriften (gleichgültig ob parallel zu einer gedruckten Ausgabe oder ausschliesslich elektronisch, ob zur Gänze oder nur teilweise online). Informationswissenschaft (IW) steht hier für den gesamten Bereich der Bibliotheks-, Informations- und Dokumentationswissenschaft und -praxis (ohne Archiv- und Museumswesen). Webliographisch bedeutet, dass sich die Betrachtung auf Informationssammlungen und Nachweise im WWW beschränkt. Bei den (frei verfügbaren) Webliographien zu EJournals handelt es sich in der Regel um Datenbanken, Verzeichnisse und Linksammlungen. Es mag vielleicht überraschen, dass für das gewählte Fachgebiet eine nahezu unüberschaubare Zahl solcher Nachweise existiert. Zwar scheint dies noch nicht zur Herausbildung von "Webliographien der Webliographien" geführt zu haben, die auf Nachweise von ausschliesslich informationswissenschaftlichen EJournals spezialisiert wären, doch in den diversen fachspezifischen Linksammlungen und Verzeichnissen werden die Sekundärpublikationen, meist in die Auflistung der Primärpublikationen gemischt, durchaus verzeichnet. Fachübergreifend existieren Kompilationen von Verzeichnissen elektronischer Zeitschriften sehr wohl. Als deutsches Beispiel kann der Abschnitt "Elektronische Zeitschriften" der Düsseldorfer Virtuellen Bibliothek angeführt werden, wo Ressourcen und Verzeichnisse/ Datenbanken elektronischer Zeitschriften vorgestellt werden; ein internationales Beispiel ist die auf dem Server der University of Vermont gewartete umfangreiche Zusammenstellung Serials in Cyberspace.

    Abstract
    In der Arbeit werden verschiedene Kennziffern zur Messung der Internationalität der Forschung untersucht. Die Grundlage bilden die Daten des Science Citation Index (SCI) von 1980 bis 2002 in der CD-ROM Version. Alle betrachteten Kennziffern weisen einen einheitlichen Gesamttrend in diesem Zeitraum auf der die Hypothese der Zunahme der Internationalität in der Forschung bestätigt. Zwei Kennziffern, der mittlere Anteil eines Landes an einem Artikel und die Diversität, gemessen durch die Shannonsche Entropie des Vektors der Anteile der Länder am SCI, zeigen eine charakteristische Verstärkung der Trends ab 1987, was für eine erhöhte Zunahme des Internationalisierungsprozesses der Forschung ab Mitte der 80er Jahre des vergangenen Jahrhunderts spricht. Darüber hinaus werden Zusammenhänge zwischen der ökonomischen Leistung eines Landes, seinem Anteil am SCI und seiner internationalen Forschungskooperation aufgezeigt.

    Abstract
    Die Szientometrie untersucht quantitative Dimensionen der wissenschaftlichen Entwicklung. Ihre Methoden und Ergebnisse werden auch zur Evaluation des wissenschaftlichen Outputs herangezogen. Ohne ein grundsätzliches Verständnis über die begrenzte Aussagefähigkeit massenstatistischer Datenerhebungen besteht die Gefahr der Fehlinterpretation, da sich , Wissenschaftlichkeit' nicht allein mit diesem Instrumentarium messen lässt. Im vorliegenden Beitrag wird darauf Bezug genommen, indem die Versuche geschildert werden, anhand der Publikationsziffern zwischen Universitäten und innerhalb von Universitäten Rangfolgen mit finanziellen Auswirkungen zu bilden. Ein zweites Thema ist die Kritik an der vermuteten Qualität von peer reviewed-Zeitschriften, die bei der quantitativen Messung eine Vorzugsstellung genießen. Ein drittes Thema ist die kritische Betrachtung des für Zeitschriften ermittelten impact factor als untaugliches Instrument der qualitativen Positionierung von Forschungsleistungen.

    Abstract
    Ein Wandel bibliometrischer Profile von Forschungsinstituten kann als besonderer Indikator für die Herausbildung neuartiger, insbesondere interdisziplinärer Forschungssituationen verstanden werden. Vergleichende Untersuchungen über bibliometrische Profile in der Wissenschaft gründen sich auf die Zählung von Publikationen, Autor- und Koautorschaft. Mit Publikationen bieten Forscher ihre Entwicklung von Problem und Methode, ihren Wissensgewinn dem wissenschaftlichen Meinungsstreit an. In diesem Zusammenhang können Zeitschriftenpublikationen an der Forschungsfront einer jeden Einzelwissenschaft - wegen des jeweiligen Standards bei der Abfassung von Zeitschriftenpublikationen - sowohl hinsichtlich ihrer Anzahl wie auch ihrer Koautorschaft und Zitationsrate verglichen werden. In unseren Untersuchungen gehen wir von folgender Definition aus: Bibliometrische Profile in der Wissenschaft sind Zusammenhänge zwischen der Anzahl von Publikationen, Zitation, Autor- und Koautorschaft, die durch funktionale Abhängigkeiten bestimmt sind. Entscheidendes Merkmal interdisziplinärer Forschungssituationen ist nach unserer Meinung nicht die Zusammensetzung der Gruppe nach Ausbildung und Kompetenz in verschiedenen Disziplinen, sondern das bei einzelnen Wissenschaftlern disziplinär fehlende Wissen zur Problembearbeitung und die daraus resultierende Suche nach Methodentransfer aus anderen Spezialgebieten und die danach gestaltete Koautorschaft. Der in den Untersuchungen benutzte Indikator für den Grad der Interdisziplinarität bringt zum Ausdruck, inwieweit die zur Bearbeitung eines Problems verwendeten Methoden in einem Wissensbereich begründet sind, der verschieden von dem Wissen ist, in dem das Problem formuliert wurde. Es ist anzunehmen, dass interdisziplinäre Arbeit durch die Zusammensetzung der Gruppe aus Vertretern verschiedener Disziplinen gefördert wird. Die Arbeit mit Methoden aus anderen Gebieten erzeugt sowohl Kooperationsbedürfnis als auch Kooperationsfähigkeit, und die Kooperation entwickelt Fähigkeiten und Interesse zur interdisziplinären Arbeit.

    Abstract
    Dimensionen der Zeitschriftenszientometrie sind (1.) die Produktion der Zeitschrift (Artikel, Autoren), (2.) der Inhalt (Themen) (3.) die Rezeption (Leser), (4.) die formale Fachkommunikation (Referenzen, Zitationen) sowie (5.) die Redaktion (Redaktionspolitik, Verlag). Die Zeitschrift "BuB - Forum für Bibliothek und Information" (BuB) wird einer szientometrischen Analyse unterzogen. BuB ist die auflagenstärkste deutschsprachige Zeitschrift des Bibliotheks- und Informationswesens. Innerhalb des Beobachtungszeitraums von 1990 bis 2003 sind 4.297 Beiträge mit insgesamt 6.803 Referenzen intellektuell ausgewertet worden. Im Vergleich zu erwarteten informetrischen Regelmäßigkeiten zeigt BuB bemerkenswerte Besonderheiten: Nicht ein Top-Autor, sondern eine über Jahre hinweg recht homogene Gruppe von Verfassern dominiert die Literaturproduktion bei BuB. Bei den Referenzen zeigt sich eine sehr hohe Konzentration auf die eigene Zeitschrift. BuB gleicht einer Insel, an die nur wenige fremde Informationen angespült werden. Obwohl Männer und Frauen jeweils 50 Prozent der Beiträge erarbeiten, so gibt es doch sowohl Männerdomänen (vor allem Rezensionen, aber auch Aufsätze) als auch Frauendomänen (Kurzbeiträge und Tagungsberichte). Die Halbwertszeit der Referenzen ist mit 2,7 Jahre sehr niedrig, Halbwertszeiten zitierter Monographien sind dabei höher als die der zitierten Zeitschriftenartikel.
