    Abstract
    "Genius work," proposed by Avramescu, refers to scientific articles whose citations grow exponentially in an extended period, for example, over 50 years. Such articles were defined as "sleeping beauties" by van Raan, who quantitatively studied the phenomenon of delayed recognition. However, the criteria adopted by van Raan at times are not applicable and may confer recognition prematurely. To revise such deficiencies, this paper proposes two new criteria, which are applicable (but not limited) to exponential citation curves. We searched for genius work among articles of Nobel Prize laureates during the period of 1901-2012 on the Web of Science, finding 25 articles of genius work out of 21,438 papers including 10 (by van Raan's criteria) sleeping beauties and 15 nonsleeping-beauties. By our new criteria, two findings were obtained through empirical analysis: (a) the awakening periods for genius work depend on the increase rate b in the exponential function, and (b) lower b leads to a longer sleeping period.

    Abstract
    Citations measure an aspect of scientific quality: the impact of publications (A.F.J. van Raan, 1996). Percentiles normalize the impact of papers with respect to their publication year and field without using the arithmetic average. They are suitable for visualizing the performance of a single scientist. Beam plots make it possible to present the distributions of percentiles in the different publication years combined with the medians from these percentiles within each year and across all years.

    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).
