- Abstract
- Es wird versucht, quantitative Werte zur Messung der Informationskompetenz von Volkswirtschaften zu entwickeln. Zudem sollen Korrelationen zwischen der Informationskompetenz und der wirtschaftlichen Leistungsfähigkeit darüber Auskunft geben, wie Gesamtwirtschaft und Inforinationswirtschaft eines Landes zusammenhängen. Operationalisierung. "Informationskompetenz" wird durch den Umsatz auf nationalen Business-toBusiness-Märkten operationalisiert. Abgeleitete Größen sind Pro-KopfImport- und Exportvolumen, Informationsproduktion und -konsumtion (insgesamt und pro Kopf) sowie der Anteil der Informationswirtschaft am jeweiligen nationalen Bruttoinlandsprodukt (BIP). Datenbasis. Im Rahmen der "Member States' Study" der Europäischen Kommission wurden für den gesamten Europäischen Wirtschaftsraum (EWR; Staaten der Europäischen Union sowie Norwegen und Island) für die Jahre 1994 und 1997 Umsatzzahlen der 17 Länder erhoben. Diese Zahlen wurden auf Plausibilität überprüft und unserer Fragestellung zugrundegelegt. Ergebnisse. Der Anteil der Informationswirtschaft am BIP ist derart gering (EWR: 0,070% im Jahr 1997), daß er nahezu ignoriert werden kann. Die Korrelation zwischen dem BIP pro Kopf und der Informationskonsumtion pro Kopf ist jedoch äußerst hoch (+0,715 im Jahr 1994 und +0,642 im Jahr 1997), ebenso die Korrelation zwischen BIP pro Kopf und Informationsimport pro Kopf (+0,588 im Jahr 1994 sowie +0,583 im Jahr 1997)

- Abstract
- The goal of the scientometric analysis presented in this article was to investigate international and regional (i.e., German-language) periodicals in the field of library and information science (LIS). This was done by means of a citation analysis and a reader survey. For the citation analysis, impact factor, citing half-life, number of references per article, and the rate of self-references of a periodical were used as indicators. In addition, the leading LIS periodicals were mapped. For the 40 international periodicals, data were collected from ISI's Social Sciences Citation Index Journal Citation Reports (JCR); the citations of the 10 German-language journals were counted manually (overall 1,494 source articles with 10,520 citations). Altogether, the empirical base of the citation analysis consisted of nearly 90,000 citations in 6,203 source articles that were published between 1997 and 2000. The expert survey investigated reading frequency, applicability of the journals to the job of the reader, publication frequency, and publication preference both for all respondents and for different groups among them (practitioners vs. scientists, librarians vs. documentalists vs. LIS scholars, public sector vs. information industry vs. other private company employees). The study was conducted in spring 2002. A total of 257 questionnaires were returned by information specialists from Germany, Austria, and Switzerland. Having both citation and readership data, we performed a comparative analysis of these two data sets. This enabled us to identify answers to questions like: Does reading behavior correlate with the journal impact factor? Do readers prefer journals with a short or a long half-life, or with a low or a high number of references? Is there any difference in this matter among librarians, documentalists, and LIS scholars?
