- 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 work identifies changes in dominant topics in library and information science (LIS) over time, by analyzing the 3,121 doctoral dissertations completed between 1930 and 2009 at North American Library and Information Science programs. The authors utilize latent Dirichlet allocation (LDA) to identify latent topics diachronically and to identify representative dissertations of those topics. The findings indicate that the main topics in LIS have changed substantially from those in the initial period (1930-1969) to the present (2000-2009). However, some themes occurred in multiple periods, representing core areas of the field: library history occurred in the first two periods; citation analysis in the second and third periods; and information-seeking behavior in the fourth and last period. Two topics occurred in three of the five periods: information retrieval and information use. One of the notable changes in the topics was the diminishing use of the word library (and related terms). This has implications for the provision of doctoral education in LIS. This work is compared to other earlier analyses and provides validation for the use of LDA in topic analysis of a discipline.

- Abstract
- The aim of this paper is to visualize the history of evidence-based medicine (EBM) and to examine the characteristics of EBM development in China and the West. We searched the Web of Science and the Chinese National Knowledge Infrastructure database for papers related to EBM. We applied information visualization techniques, citation analysis, cocitation analysis, cocitation cluster analysis, and network analysis to construct historiographies, themes networks, and chronological theme maps regarding EBM in China and the West. EBM appeared to develop in 4 stages: incubation (1972-1992 in the West vs. 1982-1999 in China), initiation (1992-1993 vs. 1999-2000), rapid development (1993-2000 vs. 2000-2004), and stable distribution (2000 onwards vs. 2004 onwards). Although there was a lag in EBM initiation in China compared with the West, the pace of development appeared similar. Our study shows that important differences exist in research themes, domain structures, and development depth, and in the speed of adoption between China and the West. In the West, efforts in EBM have shifted from education to practice, and from the quality of evidence to its translation. In China, there was a similar shift from education to practice, and from production of evidence to its translation. In addition, this concept has diffused to other healthcare areas, leading to the development of evidence-based traditional Chinese medicine, evidence-based nursing, and evidence-based policy making.

- Abstract
- Examines the use of networked information sources in scholarly communication. Networked information sources are defined broadly to cover: documents and images stored on electronic network hosts; data files; newsgroups; listservs; online information services and electronic periodicals. Reports results of a survey to determine how heavily, if at all, networked information sources are cited in scholarly printed periodicals published in 1993 and 1994. 27 printed periodicals, representing a wide range of subjects and the most influential periodicals in their fields, were identified through the Science Citation Index and Social Science Citation Index Journal Citation Reports. 97 articles were selected for further review and references, footnotes and bibliographies were checked for references to networked information sources. Only 2 articles were found to contain such references. Concludes that, although networked information sources facilitate scholars' work to a great extent during the research process, scholars have yet to incorporate such sources in the bibliographies of their published articles

- Abstract
- Reports results of a bibliometric study of the authorship characteristics of articles published in 4 major information science periodicals: JASIS, Information technology and libraries, Journal of information science, and Program. The aim was to determine the details of their authors, such as: sex, occupation, affiliation, geographic distribution, and institutional affiliation. A total of 163 articles published in 1993 and written by 294 authors were analyzed. Results indicate that: men (206 or 70%) publish 3.0 times more articles than women (69 or 23,5%). Schools of library and information science contributed the most authors. The majority of authors came from the USA (148 or 50,3%), with the Midwest region claiming the largest share (110 or 25,0%). Academic libraries (110 or 37,4%) account for the major share of library publication. 12 schools of library and information science, in the USA, contributed 32 authors (50,0%) and assistant professors (25 or 39,1%) publish the most in these library schools. Male school of library and information science authors publish 1,6 times more than their female counterparts

- 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.

- Abstract
- The domain of knowledge organization (KO) represents a foundational area of information science. One way to better understand the intellectual structure of the KO domain is to apply bibliometric methods to key contributors to the literature. This study analyzes the most prolific contributing authors to the journal Knowledge Organization, the sources they cite and the citations they receive for the period 1993 to 2016. The analyses were conducted using visualization outcomes of citation, co-citation and author bibliographic coupling analysis to reveal theoretical points of reference among authors and the most prominent research themes that constitute this scientific community. Birger Hjørland was the most cited author, and was situated at or near the middle of each of the maps based on different citation relationships. The proximities between authors resulting from the different citation relationships demonstrate how authors situate themselves intellectually through the citations they give and how other authors situate them through the citations received. There is a consistent core of theoretical references as well among the most productive authors. We observed a close network of scholarly communication between the authors cited in this core, which indicates the actual role of the journal Knowledge Organization as a space for knowledge construction in the area of knowledge organization.
