    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
    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
    We investigated the similarities of pairs of articles that are cocited at the different cocitation levels of the journal, article, section, paragraph, sentence, and bracket. Our results indicate that textual similarity, intellectual overlap (shared references), author overlap (shared authors), proximity in publication time all rise monotonically as the cocitation level gets lower (from journal to bracket). While the main gain in similarity happens when moving from journal to article cocitation, all level changes entail an increase in similarity, especially section to paragraph and paragraph to sentence/bracket levels. We compared the results from four journals over the years 2010-2015: Cell, the European Journal of Operational Research, Physics Letters B, and Research Policy, with consistent general outcomes and some interesting differences. Our findings motivate the use of granular cocitation information as defined by meaningful units of text, with implications for, among others, the elaboration of maps of science and the retrieval of scholarly literature.

    Blaise Cronin hat 2013 die Frage formuliert, ob es so etwas wie einen Kanon der Informationswissenschaft gibt. Er schlägt vor, zur Ermittlung des Kanons auch Namens- und Sachregister von einschlägigen Lehrbüchern informetrisch auszuwerten. Untersucht wurden englischsprachige Publikationen aus der Kategorie Information Science & Library Science der Fachdatenbank Web of Science sowie neun ausgewählte Lehrbücher der Informationswissenschaft. Im Web of Science wurden über 324.000 Publikationen ermittelt. Im Rahmen der szientometrischen Analyse wurden Zitationen, Publikationen und Themen ausgewertet. Zusätzlich zur klassischen Auswertung der Datenbankdokumente wurde erstmals eine Registeranalyse bei den Lehrbuchdokumenten durchgeführt. Die unterschiedlichen Ergebnisse wurden zusammengefasst, um einen gemeinsamen Kanon der Informationswissenschaft bilden zu können.

    Abstract
    Der oft zitierte Slogan "publish or perish" ist vielen ein Begriff. Er verweist darauf, dass Wissenschaftlerinnen und Wissenschaftler zunehmend danach bewertet werden, wo und wie viel sie publizieren. Auch Berufungskommissionen legen Wert auf eine umfangreiche Publikationsliste. Artikel in den "Top-Journals" eines Fachgebiets sind also die Währung, mit der in der wissenschaftlichen Community gehandelt wird. Doch woran lässt sich festmachen, welchen Einfluss eine Zeitschrift in der Fach-Community hat? In den letzten Jahrzehnten hat sich hierfür der Journal Impact Factor (JIF) als klassischer Vergleichswert etabliert. Der JIF berechnet den "Einfluss" einer Fachzeitschrift anhand der durchschnittlichen Anzahl von Zitaten, die ein darin veröffentlichter Artikel erreicht.

    Abstract
    Dieser Beitrag beschreibt a) die Ergebnisse einer Literaturstudie zur qualitativen Wahrnehmung wissenschaftlicher Publikationen, b) die Konstruktion eines daraus abgeleiteten Kriterienkatalogs zur Wahrnehmung der Qualität wissenschaftlicher Publikationen sowie c) der Überprüfung dieses Katalogs in qualitativen Interviews mit Wissenschaflterinnen und Wissenschaftlern aus dem Fachspektrum Chemie, Physik, Biologie, Materialwissenschaft und Engineering. Es zeigte sich, dass die Wahrnehmung von Qualität auf äußerlichen und von außen herangetragenen Faktoren, inhaltlichen / semantischen Faktoren und sprachlichen, syntaktischen sowie strukturellen Faktoren beruht.

    Abstract
    Der Artikel ist Teil einer größeren Untersuchung zu den Potentialen von Open Access Publishing zur Erhöhung der Publikations- und damit Karrierechancen von Sozialwissenschaftlerinnen. Es werden drei inhaltlich und methodisch ähnliche sozialwissenschaftliche Zeitschriften verglichen: das Open-Access-Journal "Forum Qualitative Sozialforschung" ("FQS") und die zwei Closed-Access-/Hybridjournale "Zeitschrift für qualitative Forschung" und "Sozialer Sinn". Erhoben wird (a) der jeweilige Frauenanteil unter Redaktions- und Beiratsmitgliedern dieser drei Zeitschriften (N=184 insgesamt), (b) aufwändig rekonstruiert und analysiert wird die Genderstruktur der Autorenschaften aller in den drei Zeitschriften zwischen 2000 und 2008 veröffentlichten Beiträge (Totalerhebung, N=1557 insgesamt).
