    Abstract
    This article challenges recent research (Evans, 2008) reporting that the concentration of cited scientific literature increases with the online availability of articles and journals. Using Thomson Reuters' Web of Science, the present article analyses changes in the concentration of citations received (2- and 5-year citation windows) by papers published between 1900 and 2005. Three measures of concentration are used: the percentage of papers that received at least one citation (cited papers); the percentage of papers needed to account for 20%, 50%, and 80% of the citations; and the Herfindahl-Hirschman index (HHI). These measures are used for four broad disciplines: natural sciences and engineering, medical fields, social sciences, and the humanities. All these measures converge and show that, contrary to what was reported by Evans, the dispersion of citations is actually increasing.

    Abstract
    Purpose - The purpose of this paper is to analyse the global scientific outputs of ontology research, an important emerging discipline that has huge potential to improve information understanding, organization, and management. Design/methodology/approach - This study collected literature published during 1900-2012 from the Web of Science database. The bibliometric analysis was performed from authorial, institutional, national, spatiotemporal, and topical aspects. Basic statistical analysis, visualization of geographic distribution, co-word analysis, and a new index were applied to the selected data. Findings - Characteristics of publication outputs suggested that ontology research has entered into the soaring stage, along with increased participation and collaboration. The authors identified the leading authors, institutions, nations, and articles in ontology research. Authors were more from North America, Europe, and East Asia. The USA took the lead, while China grew fastest. Four major categories of frequently used keywords were identified: applications in Semantic Web, applications in bioinformatics, philosophy theories, and common supporting technology. Semantic Web research played a core role, and gene ontology study was well-developed. The study focus of ontology has shifted from philosophy to information science. Originality/value - This is the first study to quantify global research patterns and trends in ontology, which might provide a potential guide for the future research. The new index provides an alternative way to evaluate the multidisciplinary influence of researchers.

    Abstract
    In der Bibliometrie werden meist zwei Größen vermessen: die Anzahl von Publikationen und Zitationen. Publiziert und zitiert haben Menschen bereits sehr früh in der Geschichte. Schon in der Antike sind bei überlieferten Werken Zitationen zu finden. Der englische Begriff "Bibliometrics" selbst wurde aber erst 1969 definiert. In dem folgenden Artikel wird eine kleine Frühgeschichte der Bibliometrie, einer Unterdisziplin der Informationswissenschaft, bis zu diesem wichtigen Jahr anhand von beispielhaften Studien und Arbeiten dargestellt. Es wird auf die Anfänge von Publikationen und Zitationen und den fachlichen Rahmen der Bibliometrie eingegangen. Der Ursprung der Bibliometriegeschichte selbst wird von unterschiedlichen Autoren unterschiedlich früh angesetzt. Die verschiedenen Ansätze werden vorgestellt und diskutiert. Der Artikel schließt mit einer Beschreibung der wachsenden Bedeutung dieses Fachs im heutigen Informationszeitalter.

    Abstract
    This article provides the first historical analysis of the relationship between collaboration and scientific impact using three indicators of collaboration (number of authors, number of addresses, and number of countries) derived from articles published between 1900 and 2011. The results demonstrate that an increase in the number of authors leads to an increase in impact, from the beginning of the last century onward, and that this is not due simply to self-citations. A similar trend is also observed for the number of addresses and number of countries represented in the byline of an article. However, the constant inflation of collaboration since 1900 has resulted in diminishing citation returns: Larger and more diverse (in terms of institutional and country affiliation) teams are necessary to realize higher impact. The article concludes with a discussion of the potential causes of the impact gain in citations of collaborative papers.

    Abstract
    According to the bibliographical data included in the Web of Science, SCOPUS, Chemical Abstracts, and other specialized information services covering the period 1900-1950, the first publications in mainstream journals by Mexican researchers appeared only in the first decades of the 20th century. Contrary to expectations, we find that the academic community was not the protagonist in the early stages of Mexican scientific practices, but that there was a strong contribution coming from researchers associated with the public-health sector and the chemical and mining industries. We were able to identify in this half century four different modes of scientific production: amateur, institutional, academic, and industrial, which in turn correspond to distinct stages in the evolution of the Mexican scientific production. We characterize these modes of production with a variety of indicators: publication and citation patterns, author output, journal and subject categories, institutional collaborations, and geographical distribution.

    Abstract
    In this study, reference standards and reference multipliers are suggested as a means to compare the citation impact of earlier research publications in physics (from the period of "Little Science" in the early 20th century) with that of contemporary papers (from the period of "Big Science," beginning around 1960). For the development of time-specific reference standards, the authors determined (a) the mean citation rates of papers in selected physics journals as well as (b) the mean citation rates of all papers in physics published in 1900 (Little Science) and in 2000 (Big Science); this was accomplished by relying on the processes of field-specific standardization in bibliometry. For the sake of developing reference multipliers with which the citation impact of earlier papers can be adjusted to the citation impact of contemporary papers, they combined the reference standards calculated for 1900 and 2000 into their ratio. The use of reference multipliers is demonstrated by means of two examples involving the time adjusted h index values for Max Planck and Albert Einstein.

    Abstract
    Vom 14. bis 17. Juli fand in Rio de Janeiro die 12th International Conference on Scientometrics and Informetrics statt. Das von den Organisatoren formulierte Ziel der Tagung war es, ein internationals Forum für Wissenschaftler, Wissenschaftsmanager und im Informationsbereich Tätige zu bieten, um den gegenwärtigen Stand und die Fortschritte im Feld szientometrischer Theorien und Anwendungen zu diskutieren. Nachdem die letzten beiden Konferenzen in Europa stattgefunden hatten (Stockholm und Madrid), war mit der Wahl des Tagungsortes zudem der Anspruch verknüpft, einen Beitrag zur weiteren Verbreitung der Szientometrie in lateinamerikanischen Ländern zu leisten. Die Konferenz verzeichnete die in ihrer bisherigen Geschichte höchste Zahl von eingereichten Beiträgen (254), von denen 66 Prozent angenommen wurden. Das endgültige Programm umfasste damit zwei Keynotes, über 90 Vorträge in 21 Sessions sowie 64 Poster. Vor dem Beginn dieses Hauptprogramms der Konferenz fanden darüber hinaus ein Doctoral Forum und drei Workshops zu den Themen "Tracking and evaluating interdisciplinary research: metric and maps", "Visualizing and Analyzing Scientific Literature with CiteSpace" und "Using Maps of Science to Teach Science" statt.
