Although there is evidence that counting the readers of an article in the social reference site, Mendeley, may help to capture its research impact, the extent to which this is true for different scientific fields is unknown. This study compares Mendeley readership counts with citations for different social sciences and humanities disciplines. The overall correlation between Mendeley readership counts and citations for the social sciences was higher than for the humanities. Low and medium correlations between Mendeley bookmarks and citation counts in all the investigated disciplines suggest that these measures reflect different aspects of research impact. Mendeley data was also used to discover patterns of information flow between scientific fields. Comparing information flows based on Mendeley bookmarking data and cross disciplinary citation analysis for the disciplines revealed substantial similarities and some differences. Thus, the evidence from this study suggests that Mendeley readership data could be used to help capture knowledge transfer across scientific disciplines, especially for people that read but do not author articles, as well as giving impact evidence at an earlier stage than is possible with citation counts.

faculty members from North America to examine differ-ences between Scopus and Web of Science in assess-ing the scholarly impact of the field focusing on the most frequently citing journals, conference proceedings, research domains and institutions, as well as all citing countries. Results show that when assessment is lim-ited to smaller citing entities (e.g., journals, conference proceedings, institutions), the two databases produce considerably different results, whereas when assess-ment is limited to larger citing entities (e.g., research domains, countries), the two databases produce very similar pictures of scholarly impact. In the former case, the use of Scopus (for journals and institutions) and both Scopus and Web of Science (for conference proceed-ings) is necessary to more accurately assess or visualize the scholarly impact of IS, whereas in the latter case, assessing or visualizing the scholarly impact of IS is independent of the database used.

This study uses citations to a group of 42 LIS faculty members to examine the differences between Scopus and WoS in mapping the faculties ’ intellectual impact, focusing on the sources of their citations by universities, journals, and countries. The study also examines the effects of adding Scopus data on results obtained from WoS. Findings show that while Scopus does not significantly influence the rankings of the top citing journals, institutions, or countries, the database is necessary to use in addition to WoS in order to accurately map the intellectual impact of the faculty members examined and identify more correctly the extent of their research influence on the wider scientific community. Researchers using citations to identify, map, or visualize the intellectual impact of authors, projects, programs, journals, knowledge domains, and countries often rely on data exclusively from ISI databases (Börner, Chen, & Boyack, 2003; Goldstone & Leydesdorff, 2006; McKechnie, Goodall, Lajoie-Paquette, & Julien, 2005). This reliance on ISI databases is partially due to the fact that the databases (currently offered through what is known as Web of Science-WoS) were for decades the only comprehensive citation data sources that

Abstract We introduce a new metric for interdisciplinarity, based on co-author publication history. A published article that has co-authors with quite different publication histories can be deemed relatively "interdisciplinary," in that the article reflects a convergence of previous research in distinct sets of publication outlets. In recent work, we have shown that this interdisciplinarity metric can predict citations. Here, we show that the journal Cognitive Science tends to contain collaborations that are relatively high on this interdisciplinarity metric, at about the 80th percentile of all journals across both social and natural sciences. Following on Goldstone and Leydesdorff (2006), we describe how scientometric tools provide a valuable means of assessing the role of cognitive science in broader scientific work, and also as a tool to investigate teamwork and distributed cognition. We describe how data-driven metrics of this kind may facilitate this exploration without relying upon rapidly changing discipline and topic keywords associated with publications.

Purpose: to provide a view and analysis of the immediate field of journals which surround a number of key heterodox economics journals. Design/methodology/approach: Using citation data from the Science and Social Science Citation Index, the individual and collective networks of a number of journals in this field are analyzed. Findings: The size and shape of the citation networks of journals can differ substantially, even if in a broadly similar category. Heterodox economics cannot (yet) be considered as an integrated specialty: authors in several journals in heterodox economics cite more from mainstream economics than from other heterodox journals. There are also strong links with other disciplinary fields such as geography, development studies, women studies, etc. Research limitations/implications: The analysis is limited by its reliance on citation data in the Science and Social Science Citation Indexes provided by the Thomson-Scientific. Practical implications: The analysis shows not only where journals draw their strengths from, but also how knowledge between journals and neighbouring sub-fields is diffused. This can be important for editors, authors, and others. Originality/value: A network analysis focusing not just on a single journal as a focal point, but combining several journals in a single analysis enables us to visualize structural properties of the field of heterodox economics which otherwise remain latent. This study provides a structural approach to citation analysis as a tool for the study of scientific specialties.

The authors describe a large-scale, longitudinal citation analysis of intellectual trading between information stud-ies and cognate disciplines. The results of their investi-gation reveal the extent to which information studies draws on and, in turn, contributes to the ideational sub-strates of other academic domains. Their data show that the field has become a more successful exporter of ideas as well as less introverted than was previously the case. In the last decade, information studies has begun to con-tribute significantly to the literatures of such disciplines as computer science and engineering on the one hand and business and management on the other, while also drawing more heavily on those same literatures.
Adding the dimension of knowledge trading to source impact assessment: Approaches, indicators, and implications

The objective of this paper is to systematically assess sources ’ (e.g., journals ’ and proceedings’) impact in knowledge trading. While there were efforts in evaluating different aspects of journal impact, the dimension of knowledge trading was largely absent. To fill the gap, this study employs a set of trading-based indicators, including weighted degree centrality, Shannon entropy, and weighted betweenness centrality, to assess sources ’ trading impact. These indicators are applied to several time-sliced source-to-source citation networks that comprise 33,634 sources indexed in the Scopus database. Results show that

This paper discovers patterns of knowledge dissemination among scientific disciplines. While the transfer of knowledge is largely unobservable, citations from one discipline to another have been proven to be an effective proxy to study disciplinary knowledge flow. This study constructs a knowledge flow network in that a node represents a Journal Citation Report subject category and a link denotes the citations from one subject category to another. Using the concept of shortest path, several quantitative measurements are proposed and applied to a knowledge flow network. Based on an examination of subject categories in Journal Citation Report, this paper finds that social science domains tend to be more self-contained and thus it is more difficult for knowledge from other domains to flow into them; at the same time, knowledge from science domains, such as biomedicine-, chemistry-, and physics-related domains can access and be accessed by other domains more easily. This paper also finds that social science domains are more disunified than science domains, as three fifths of the knowledge paths from one social science domain to another need at least one science domain to serve as an intermediate. This paper contributes to discussions on disciplinarity and interdisciplinarity by providing empirical analysis.
