  Abstract

Our study examines the suitability of Scopus for bibliometric analyses in comparison with the Web of Science (WOS). In particular we want to explore if the outcome of bibliometric analyses differs between Scopus and WOS and, if yes, in which aspects. Since journal indicators vary among disciplines, we analysed only journals from the subject pharmacy and pharmaceutical sciences. Nonetheless, our study has also broader implications. Its major findings are: (a) Each top-100 JCR pharmacy journal was covered by Scopus. (b) The impact factor was higher for 82 and the immediacy index greater for 78 journals in Scopus in 2005. Pharmacy journals with a high impact factor in the JCR usually have a high impact factor in Scopus. (c) Several medium impact journals could be identified in Scopus which were not reported in JCR. (d) The two databases differed in the number of articles within a tolerable margin of deviation for most journals.

Key Words: bibliometric analysis; comparison of databases; data reliability; impact factor; Journal Citation Reports; Scopus; Web of Science
