Abstract

Reports results of a study to investigate the place and role of citation analysis in selected disciplines in the social sciences, including library and information science. 5 core library and information science periodicals: Journal of documentation; Library quarterly; Journal of the American Society for Information Science; College and research libraries; and the Journal of information science, were studed to determine the percentage of articles devoted to citation analysis and develop an indictive typology to categorize the major foci of research being conducted under the rubric of citation analysis. Similar analysis was conducted for periodicals in other social sciences disciplines. Demonstrates how the rubric can be used to dertermine how citatiion analysis is applied within library and information science and other disciplines. By isolating citation from bibliometrics in general, this work is differentiated from other, previous studies. Analysis of data from a 10 year sample of transdisciplinary social sciences literature suggests that 2 application areas predominate: the validity of citation as an evaluation tool; and impact or performance studies of authors, periodicals, and institutions

Abstract

In a series of articles, Don Swanson explores the problem of associating two or more literatures that are logically, or substantively, related, but bibliographically noninteractive. He has called these implicit links among published literatures undicovered public knowledge. This article explores the fate of Swanson's ideas, using citation content analysis both to determine which authors have utilized Swanson's ideas and to examine the uses to which they have been put. The results suggest that while Swanson has received significant attention from the library and information science community, his ideas have not been widely cited in biomedical disciplines, and, when cited, only with rhetorically dismissive qualifications that detracts from their facticity. These results are interpreted as a failed instance of interdisciplinarity communication, and several explanations of this failure are discussed

Abstract

During the past decades, journal impact data obtained from the Journal Citation Reports (JCR) have gained relevance in library management, research management and research evaluation. Hence, both information scientists and bibliometricians share the responsibility towards the users of the JCR to analyse the reliability and validity of its measures thoroughly, to indicate pitfalls and to suggest possible improvements. In this article, ageing patterns are examined in 'formal' use or impact of all scientific journals processed for the Science Citation Index (SCI) during 1981-1995. A new classification system of journals in terms of their ageing characteristics is introduced. This system has been applied to as many as 3,098 journals covered by the Science Citation Index. Following an earlier suggestion by Glnzel and Schoepflin, a maturing and a decline phase are distinguished. From an analysis across all subfields it has been concluded that ageing characteristics are primarily specific to the individual journal rather than to the subfield, while the distribution of journals in terms of slowly or rapidly maturing or declining types is specific to the subfield. It is shown that the cited half life (CHL), printed in the JCR, is an inappropriate measure of decline of journal impact. Following earlier work by Line and others, a more adequate parameter of decline is calculated taking into account the size of annual volumes during a range of fifteen years. For 76 per cent of SCI journals the relative difference between this new parameter and the ISI CHL exceeds 5 per cent. The current JCR journal impact factor is proven to be biased towards journals revealing a rapid maturing and decline in impact. Therefore, a longer term impact factor is proposed, as well as a normalised impact statistic, taking into account citation characteristics of the research subfield covered by a journal and the type of documents published in it. When these new measures are combined with the proposed ageing classification system, they provide a significantly improved picture of a journal's impact to that obtained from the JCR.
