    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
    Bibliometrie zur Evaluation wissenschaftlicher Leistung gewinnt zunehmend an Bedeutung. Vor allem für Hochschulleitungen sind bibliometrische Indices zur Leistungsbeurteilung ihrer Wissenschaftler attraktiv. Die Wissenschaftler hingegen stehen den bibliometrischen Analysen skeptisch gegenüber und nehmen die Indices nur zögerlich an, wie die geringe Nutzung auf ihren Homepages im Internet zeigt. Für Bibliotheken ergibt sich eine neue Aufgabe. Sie sollten sich als Partner beider Gruppen positionieren und durch aktive Beratung ihre Kompetenz auf diesem Feld einbringen.

    Abstract
    Zitationen spielen eine wichtige Rolle im wissenschaftlichen Diskurs, in der Recherchepraxis sowie im Bereich der Bibliometrie. In jüngster Zeit gibt es zunehmend Initiativen, die Zitationen als Open Data zur freien Nachnutzung verfügbar machen. Der Beitrag beschreibt den Stand der Entwicklung dieser Initiativen und zeigt, dass in nächster Zeit eine kritische Masse von Daten entstehen könnte, aus denen sich gerade für Bibliotheken neue Perspektiven ergeben. Als konkrete Möglichkeit zur Partizipation für Bibliotheken wird das DFG-Projekt Linked Open Citation Database (LOC-DB) vorgestellt.

    Abstract
    This article studies the impact of differences in citation practices at the subfield, or Web of Science subject category level, using the model introduced in Crespo, Li, and Ruiz-Castillo (2013a), according to which the number of citations received by an article depends on its underlying scientific influence and the field to which it belongs. We use the same Thomson Reuters data set of about 4.4 million articles used in Crespo et al. (2013a) to analyze 22 broad fields. The main results are the following: First, when the classification system goes from 22 fields to 219 subfields the effect on citation inequality of differences in citation practices increases from ?14% at the field level to 18% at the subfield level. Second, we estimate a set of exchange rates (ERs) over a wide [660, 978] citation quantile interval to express the citation counts of articles into the equivalent counts in the all-sciences case. In the fractional case, for example, we find that in 187 of 219 subfields the ERs are reliable in the sense that the coefficient of variation is smaller than or equal to 0.10. Third, in the fractional case the normalization of the raw data using the ERs (or subfield mean citations) as normalization factors reduces the importance of the differences in citation practices from 18% to 3.8% (3.4%) of overall citation inequality. Fourth, the results in the fractional case are essentially replicated when we adopt a multiplicative approach.

    Abstract
    This article studies massive evidence about references made and citations received after a 5-year citation window by 3.7 million articles published in 1998 to 2002 in 22 scientific fields. We find that the distributions of references made and citations received share a number of basic features across sciences. Reference distributions are rather skewed to the right while citation distributions are even more highly skewed: The mean is about 20 percentage points to the right of the median, and articles with a remarkable or an outstanding number of citations represent about 9% of the total. Moreover, the existence of a power law representing the upper tail of citation distributions cannot be rejected in 17 fields whose articles represent 74.7% of the total. Contrary to the evidence in other contexts, the value of the scale parameter is above 3.5 in 13 of the 17 cases. Finally, power laws are typically small, but capture a considerable proportion of the total citations received.
