But because they are used differently than print--scientists and scholars tend to search electronically and follow hyperlinks rather than browse or peruse--electronically available journals may portend an ironic change for science. Using a database of 34 million articles, their citations (1945 to 2005), and online availability (1998 to 2005), I show that as more journal issues came online, the articles referenced tended to be more recent, fewer journals and articles were cited, and more of those citations were to fewer journals and articles. The forced browsing of print archives may have stretched scientists and scholars to anchor findings deeply into past and present scholarship. Searching online is more efficient and following hyperlinks quickly puts researchers in touch with prevailing opinion, but this may accelerate consensus and narrow the range of findings and ideas built upon. 10.1126/science.1150473 Electronic Publication and the Narrowing of Science and Scholarship James Evans doi:10.1126/science.1150473 Science, Vol. 321, No. 5887.

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. 10.1177/0165551507086991 A bibliometric analysis of pharmacology and pharmacy journals: Scopus versus Web of Science Juan Gorraiz Christian Schloegl doi:10.1177/0165551507086991 Journal of Information Science (3 April 2008), 0165551507086991. 2008-04-03T15:01:21-00:00 2008 Journal of Information Science 0165551507086991 bibliometrie
