the absence of books and book chapters in the Web of Science Citation Indexes (SCI, SSCI and A&HCI) has always been considered an important flaw but the Thomson Reuters 'Book Citation Index' database was finally available in October of 2010 indexing 29,618 books and 379,082 book chapters. The Book Citation Index opens a new window of opportunities for analyzing these fields from a bibliometric ...

We study the national production of academic knowledge in all Iberoamerican and Caribbean countries between 1973 and 2007. We show that the total number of mainstream scientific publications listed in the Science Citation Index (SCI), the Social Science Citation Index (SSCI) and Arts and Humanities Citation Index (A&HCI) follows an exponential growth, the same as the national productivity expre...

Through citation analysis, this study explored the distribution of document type, language and publication year for citations in social science journals. Samples were research articles published in 2010 from first-rank journals, as assessed by the Department of Humanities and Social Sciences, National Science Council and indexed in Taiwan Social Sciences Citation Index (TSSCI).

This paper discusses the implications of the decomposition property of the Theil index in sequences of nested and hierarchic grouping structures, formalizing general results applicable to a generic sequence of grouping structures. A specific application to data on wages and employment by industrial classification to measure the evolution of wage inequality through time will be explored, analyzi...

Recent advances in methods and techniques enable us to develop an interactive overlay to the global map of science based on aggregated citation relations among the 9,162 journals contained in the Science Citation Index and Social Science Citation Index 2009 combined. The resulting mapping is provided by VOSViewer. We first discuss the pros and cons of the various options: cited versus citing, m...

This paper evaluates the content of Google Scholar and seven other databases (Academic Search Elite, AgeLine, ArticleFirst, GEOBASE, POPLINE, Social Sciences Abstracts, and Social Sciences Citation Index) within the multidisciplinary subject area of later-life migration. Each database is evaluated with reference to a set of 155 core articles selected in advance—the most important studies of lat...

This paper presents a scientometric study about information management. Both the Science Citation Index and the Social Science Citation Index were used to analyse the literature about information management by various criteria like journal subject category, origins of the authors, publication languages, chronological distribution. Furthermore, a citation analysis was conducted. On the basis of ...

2005 Science Citation Index (SCI) and Social Sciences Citation Index (SSCI) Journal Citation Reports (JCR) by analyzing the Impact Factor distributions of their journals. The distribution of the SCI journals corresponded with a distribution generally modeled by the negative binomial distribution, whereas the SSCI distribution fit the Poisson distribution modeling random, rare events. Both Impac...
