    Abstract
    In einer industriellen IuD-Stelle konnte auf der Basis vorhandener Langzeitstatistiken die funktionale Abhängigkeit der Literaturnutzung vom Alter der Literatur - in Form von Kopien aus Fachzeitschriften und von SAE-Berichten - mathematisch beschrieben und für die Praxis anwendbar gemacht werden. Grundlagen und Ermittlung der Basisdaten, deren Aufbereitung für eine mathematische Verarbeitung und ihre Darstellung als logarithmische Funktion werden erläutert. Die aus der Regelungstechnik bekannte Sprungantwortfunktion ist von der Sache her anwendbar und beschreibt das Phänomen plausibel. Die für ausgewählte Jahrgänge der betrachteten Literaturarten gefundenen Gleichungen werden in ihren Parametern diskutiert. Anhand der Resultate der Arbeit ergibt sich die Möglichkeit, eine Alterungskurve mit nur einer Zählung (statt der drei mathematisch erforderlichen) abzuschätzen. Ein Vergleich mit derBestimmung der Alterung der Nutzung auf der Basis der Zitatenanalyse zeigt, dass beide Verfahren kompatibel sind.

    Abstract
    "Im 21. Jahrhundert ist die entscheidende Herausforderung an Informationsdienstleister nicht, Informationen zugänglich, sondern sie optimal nutzbar zu machen", sagt Sabine Brünger-Weilandt, Geschäftsführerin von FIZ Karlsruhe, das den Online-Dienst STN International in internationaler Kooperation betreibt. Informationsprofis, so Brünger-Weilandt weiter, bräuchten hockentwickelte Software für strategisches Informationsmanagement. Als "Antwort auf diesen Bedarf" hat STN International eine neue Software zur Analyse und Visualisierung (A&V) von Rechercheergebnissen aus STN-Datenbanken entwickelt. STN® AnaVistT(TM) wurde auf der DGI Online-Tagung Ende Mai in Frankfurt am Main und auf Benutzertreffen in Frankfurt am Main, München und Essen vorgestellt. Seit 18. Juli 2005 ist das neue A&V-Werkzeug für die öffentliche Nutzung freigegeben (www.stn-international.de).

    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.
