    Abstract
    Wissenschaftliche Karrieren und Publikationen benötigen Reputation und möglichst viel Beachtung. Literatur, die diese Aufmerksamkeit findet, wird - so die gängige Annahme - häufig zitiert. Ausgehend von dieser Überlegung wurden Verfahren der Zitationsmessung entwickelt, die Auskunft über die Relevanz oder (wie im- und explizit oft auch postuliert wird) gar die Qualität einer Publikation oder eines Wissenschaftlers geben sollen.

    Abstract
    Fachzeitschriften spielen für Wissenschaftler und Praktiker bei der Verbreitung von Forschungsergebnissen und Erfahrungsberichten eine wichtige Rolle. Der vorliegende Artikel gibt eine kurze Einführung in das Feld der Informetrie, um auf dieser Grundlage eine Zeitschriftenliste auf dem Gebiet der lnformations- und Bibliothekswissenschaft (luB) einzuführen. Durch Kombination von zehn verschiedenen Zeitschriftenlisten aus Datenbanken, die relevante Literatur auf dem Gebiet der luB erfassen, wird eine umfassende Liste von 1205 relevanten Fachzeitschriften erstellt. Anhand ihrer Erscheinungshäufigkeit wird die Bedeutung einzelner Zeitschriften für das Gebiet der luB eingeordnet, wobei vier verschiedene Kategorien von Zeitschriften unterschieden werden: fünfzehn Kernzeitschriften, 88 zentrale Zeitschriften, 173 selektive Zeitschriften und 672 Randzeitschriften. Betrachtet werden darüber hinaus auch Publikationssprache und geografische Verteilung der Zeitschriften sowie die Überschneidung von verschiedenen Datenbanken untereinander.

    Abstract
    In einer szientometrischen bzw. informetrischen Studie werden internationale wie deutschsprachige Zeitschriften der Informations-/Bibliothekswissenschaft und -praxis mittels Zitationsanalyse und Expertenbefragung analysiert. Die zitatenanalytischen Kennwerte umfassen den Impact Factor, die Halbwertszeit, die Zitierfreudigkeit, die relative Häufigkeit von Zeitschriftenselbstreferenzen sowie Soziogramme der einflussreichen Periodika. Der Fragebogen erhebt die Lesehäufigkeit, die Einsetzbarkeit der gelesenen Journale im Tätigkeitsbereich, die Publikationstätigkeit und die Publikationspräferenz sowohl für alle Respondenten als auch für abgrenzbare Gruppen (Praktiker vs. Wissenschaftler, Bibliothekare vs. Dokumentare vs. Informationswissenschaftler, öffentlicher Dienst vs. Informationswirtschaft vs. andere Wirtschaftsunternehmen).

    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 dieser Arbeit werden zwei Mehrwertdienste für Suchsysteme vorgestellt, die typische Probleme bei der Recherche nach wissenschaftlicher Literatur behandeln können. Die beiden Mehrwertdienste semantische Heterogenitätsbehandlung am Beispiel Crosskonkordanzen und Re-Ranking auf Basis von Bradfordizing, die in unterschiedlichen Phasen der Suche zum Einsatz kommen, werden in diesem Buch ausführlich beschrieben und evaluiert. Für die Tests wurden Fragestellungen und Daten aus zwei Evaluationsprojekten (CLEF und KoMoHe) verwendet. Die intellektuell bewerteten Dokumente stammen aus insgesamt sieben Fachdatenbanken der Fächer Sozialwissenschaften, Politikwissenschaft, Wirtschaftswissenschaften, Psychologie und Medizin.

    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.

    Abstract
    In diesem Beitrag wird eine Publikationsanalyse von Beiträgen in von im Web of Science (WoS) indexierten bibliotheks- und informationswissenschaftlichen Zeitschriften vorgestellt. Die Ergebnisse dieser Analyse bestätigen die anglo-amerikanische Dominanz in der facheinschlägigen Literatur, die bei den primär informationswissenschaftlichen Zeitschriften sogar noch deutlicher ausfällt. Die skandinavischen Länder und der Bereich der Szientometrie stellen gewisse Ausnahmen dar. Die internationale Sichtbarkeit Deutschlands und Österreichs ist hingegen "ausbaufähig".

    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
    In diesem Beitrag werden am Beispiel von Onkologie- und Pharmaziezeitschriften Unterschiede zwischen und Gemeinsamkeiten von Downloads und Zitaten herausgearbeitet. Die Download-Daten wurden von Elsevier (ScienceDirect) bereitgestellt, die Zitationsdaten wurden den Journal Citation Reports entnommen bzw. aus dem Web of Science recherchiert. Die Ergebnisse zeigen einen hohen Zusammenhang zwischen Download- und Zitationshäufigkeiten, der für die relativen Zeitschriftenindikatoren und auf Artikelebene etwas geringer ist. Deutliche Unterschiede bestehen hingegen zwischen den Altersstrukturen der herunter-geladenen und der zitierten Artikel. Elektronische Zeitschriften haben maßgeblich dazu beigetragen, dass aktuelle Literatur früher aufgegriffen und deutlich öfter zitiert wird, im Schnitt hat sich das Alter der zitierten Literatur in den letzten zehn Jahren aber kaum verändert.

    Abstract
    In der Bibliometrie werden meist zwei Größen vermessen: die Anzahl von Publikationen und Zitationen. Publiziert und zitiert haben Menschen bereits sehr früh in der Geschichte. Schon in der Antike sind bei überlieferten Werken Zitationen zu finden. Der englische Begriff "Bibliometrics" selbst wurde aber erst 1969 definiert. In dem folgenden Artikel wird eine kleine Frühgeschichte der Bibliometrie, einer Unterdisziplin der Informationswissenschaft, bis zu diesem wichtigen Jahr anhand von beispielhaften Studien und Arbeiten dargestellt. Es wird auf die Anfänge von Publikationen und Zitationen und den fachlichen Rahmen der Bibliometrie eingegangen. Der Ursprung der Bibliometriegeschichte selbst wird von unterschiedlichen Autoren unterschiedlich früh angesetzt. Die verschiedenen Ansätze werden vorgestellt und diskutiert. Der Artikel schließt mit einer Beschreibung der wachsenden Bedeutung dieses Fachs im heutigen Informationszeitalter.

    Abstract
    Trotz großer Dokumentmengen für datenbankübergreifende Literaturrecherchen erwarten akademische Nutzer einen möglichst hohen Anteil an relevanten und qualitativen Dokumenten in den Trefferergebnissen. Insbesondere die Reihenfolge und Struktur der gelisteten Ergebnisse (Ranking) spielt, neben dem direkten Volltextzugriff auf die Dokumente, inzwischen eine entscheidende Rolle beim Design von Suchsystemen. Nutzer erwarten weiterhin flexible Informationssysteme, die es unter anderem zulassen, Einfluss auf das Ranking der Dokumente zu nehmen bzw. alternative Rankingverfahren zu verwenden. In dieser Arbeit werden zwei Mehrwertverfahren für Suchsysteme vorgestellt, die die typischen Probleme bei der Recherche nach wissenschaftlicher Literatur behandeln und damit die Recherchesituation messbar verbessern können. Die beiden Mehrwertdienste semantische Heterogenitätsbehandlung am Beispiel Crosskonkordanzen und Re-Ranking auf Basis von Bradfordizing, die in unterschiedlichen Phasen der Suche zum Einsatz kommen, werden hier ausführlich beschrieben und im empirischen Teil der Arbeit bzgl. der Effektivität für typische fachbezogene Recherchen evaluiert. Vorrangiges Ziel der Promotion ist es, zu untersuchen, ob das hier vorgestellte alternative Re-Rankingverfahren Bradfordizing im Anwendungsbereich bibliographischer Datenbanken zum einen operabel ist und zum anderen voraussichtlich gewinnbringend in Informationssystemen eingesetzt und dem Nutzer angeboten werden kann. Für die Tests wurden Fragestellungen und Daten aus zwei Evaluationsprojekten (CLEF und KoMoHe) verwendet. Die intellektuell bewerteten Dokumente stammen aus insgesamt sieben wissenschaftlichen Fachdatenbanken der Fächer Sozialwissenschaften, Politikwissenschaft, Wirtschaftswissenschaften, Psychologie und Medizin. Die Evaluation der Crosskonkordanzen (insgesamt 82 Fragestellungen) zeigt, dass sich die Retrievalergebnisse signifikant für alle Crosskonkordanzen verbessern; es zeigt sich zudem, dass interdisziplinäre Crosskonkordanzen den stärksten (positiven) Effekt auf die Suchergebnisse haben. Die Evaluation des Re-Ranking nach Bradfordizing (insgesamt 164 Fragestellungen) zeigt, dass die Dokumente der Kernzone (Kernzeitschriften) für die meisten Testreihen eine signifikant höhere Precision als Dokumente der Zone 2 und Zone 3 (Peripheriezeitschriften) ergeben. Sowohl für Zeitschriften als auch für Monographien kann dieser Relevanzvorteil nach Bradfordizing auf einer sehr breiten Basis von Themen und Fragestellungen an zwei unabhängigen Dokumentkorpora empirisch nachgewiesen werden.

    Abstract
    This paper has a dual character dictated by its twofold purpose. First, it is a speculative historiographic essay containing an attempt to fix the present posotion of library and information science within the context of the probabilisitc revolution that has been encompassing all of science. Second, it comprises a guide to practitioners engaged in statistical research in library and information science

    Abstract
    Data were gathered on acknowledgements in five leading information science journals for the years 1991-1999. The results were compared with data from two earlier studies of the same journals. Analysis of the aggregate data (1971-1999) confirms the general impression that acknowledgement has become an institutionalised element of the scholarly communication process, reflecting the growing cognitive and structural complexity of contemporary research.

    Abstract
    Im vorliegenden Beitrag wird eine bibliometrische Analyse des Dokumentlieferdienstes Subito vorgestellt. Der Aufsatz ist folgendermaßen gegliedert: Nach einer kurzen Einführung folgt eine Beschreibung von Subito. Den Hauptteil der Arbeit stellt die bibliometrische Analyse dar. Bei dieser wird zunächst untersucht, ob ein großer Anteil der bei Subito bestellten Artikel von relativ wenigen Periodika abgedeckt werden kann. Weiters wird der Frage nachgegangen,ob sich Konzentrationsmuster auch in Hinblick auf den Marktanteil der Verlage erkennen lassen. Danach wird die fachliche Verteilung jener 100 Periodika genauer analysiert, von denen bei Subito die meisten Aufsätze bestellt werden. Schließlich wird herausgearbeitet, ob sich ein Zusammenhang zwischen den Bestellhäufigkeiten von Zeitschriften bei Subito und den Zitationshäufigkeiten laut den Journal Citation Reports (JCR) herstellen lässt. Am Ende des Beitrages werden die der Studie zugrunde liegenden Einschränkungen aufgezeigt und die wichtigsten Ergebnisse zusammengefasst.

    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
    Internet based electronic resources are growing dramatically but there have been no empirical studies evaluating the impact of e-sources, as a whole, on formal scholarly communication. reports results of an investigation into how much e-sources have been used in formal scholarly communication, using a case study in the area of Library and Information Science (LIS) during the period 1994 to 1996. 4 citation based indicators were used in the study of the impact measurement. Concludes that, compared with the impact of print sources, the impact of e-sources on formal scholarly communication in LIS is small, as measured by e-sources cited, and does not increase significantly by year even though there is observable growth of these impact across the years. It is found that periodical format is related to the rate of citing e-sources, articles are more likely to cite e-sources than are print priodical articles. However, once authors cite electronic resource, there is no significant difference in the number of references per article by periodical format or by year. Suggests that, at this stage, citing e-sources may depend on authors rather than the periodical format in which authors choose to publish

    Abstract
    Die Anzahl wissenschaftlicher Publikationen in Zeitschriften, die Anzahl von Zitaten in diesen Zeitschriftenartikeln und die Anzahl angemeldeter Patente steigen ständig und scheinbar unaufhaltsam. Der Einsatz von Bibliometrie eröffnet die Möglichkeit, diese Kommunikation in der Wissenschaft transparenter zu machen: So können mit Hilfe von Bibliometrie die Entwicklung von Themen nachvollzogen, die Wahrnehmung von Einrichtungen bestimmt und mögliche Kooperationspartner identifiziert werden. Der Beitrag illustriert, wie es mit Hilfe von quantitativen bibliometrischen Methoden möglich ist, einen objektiven Eindruck wissenschaftlicher Entwicklung zu gewinnen. Er befasst sich dabei mit der Frage, wie Bibliometrie im Kontext von Trendbeobachtung und Trenderkennung in der Naturwissenschaft eingesetzt werden kann und welcher Nutzen sich hieraus ergibt.
