    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
    Die Bereitstellung und Nutzung digitaler Bibliotheken entwickelt sich allmählich zum Standard der Literatur und Informationsversorgung in Wissenschaft und Forschung. Ganzen Disziplinen genügt oftmals die verfügbare digitale Information, Printmedien werden besonders im STM-Segment zu einem Nischenprodukt. Digitale Texte können beliebig eingebaut, kopiert und nachgenutzt werden, die Verlinkung zwischen Metadaten und Volltexten bringt weitere Nutzungsvorteile. Dabei sind die Angebote von Digital Libraries Bestandteil eines ganzheitlichen digitalen Ansatzes, wonach die elektronische Informations- und Literaturversorgung integraler Bestandteil von E-Science (Enhanced Science) oder Cyberinfrastructure darstellt. Hierbei verschmelzen dann Produktion, Diskussion, Distribution und Rezeption der wissenschaftlichen Inhalte auf einer einzigen digitalen Plattform. Damit sind dann nicht nur die Literatur- und Informationsversorgung (Digital Libraries), sondern auch die Wissenschaft selbst digital geworden. Diese dramatische Veränderung in der Wissenschaftskommunikation hat direkte Auswirkungen auf die Messung der Wissenschaftskommunikation, also auf die Evaluation von wissenschaftlichem Output. Bisherige Systeme der Wissenschaftsvermessung basieren hauptsächlich auf bibliometrischen Analysen, d.h. der Quantifizierung des Outputs und dessen Rezeption (Zitierhäufigkeit). Basis dafür sind insbesondere im STM-Bereich die international anerkannten Datenbanken des ISI (Thomson Scientific) insbesondere der Science Citation Index, SCI) oder vielleicht zukünftig das Konkurrenzprodukt SCOPUS des Wissenschaftskonzerns Reed Elsevier. Die Digitalisierung der Wissenschaft in ihrem kompletten Lebenszyklus, die zunehmende Nutzung und Akzeptanz von Dokumentenrepositorien, Institutsservern und anderen elektronischen Publikationsformen im Rahmen von E-Science erfordern und ermöglichen zugleich den Nachweis von Output und Rezeption durch neue bibliometrische Formen, etwa der Webometrie (Webmetrics). Im vorliegenden Paper haben wir hierzu Analysen durchgeführt und stellen eine Abschätzung vor, wie sich der Anteil von webometrisch erfassbarer und zugänglicher wissenschaftlicher Literatur im Vergleich zu Literatur, die mit den Standardsystemen nachgewiesen werden kann im Laufe der letzten Jahre verändert hat. Dabei haben wir unterschiedliche Disziplinen und Länder berücksichtigt. Zudem wird ein Vergleich der webometrischen Nachweisqualität so unterschiedlicher Systeme wie SCI, SCOPUS und Google Scholar vorgestellt.
