Comparison of Web of Science and Scopus impact factors of Indian journals.

AuthorNagaraja, Aragudige


Many periodicals and magazines have been published in India. The Directory of Indian Scientific Periodicals published from Council for Scientific and Industrial Research (CSIR) New Delhi provides information about 2000 journals published from India. Every year library budgets are decreasing. Hence librarians are facing difficulties when selecting journals for collection development. Since few national or international systematic approaches exist for journal selection, this article asserts that the best methods for librarians often include the following:

  1. Check the catalogue or collections of journals subscribed by similar type libraries.

  2. Measure the opinion of subject experts working in the same organization or others by survey or other scientific methods.

  3. Examine the impact factor (IF) of journals under consideration.

The evaluation of the quality of research is important for various professional societies, individual scientists, scholarly institutions, and funding organizations (Smith, R 2006). Even though the above mentioned three methods are scientific, most of the libraries will take the impact factors of journals as an important tool while evaluating and selecting journals. Academic librarians frequently use impact factors to help them decide which journals are important enough to subscribe to and which subscriptions may be canceled ( Barschall 1988; Coleman 2007). The best tools available to select the quality journals are JCR (Journal Citation Report) and Scimago journals rank (SJR) indicator.

JCR was the only publication source for the impact factor (IF) of journals before the introduction of the SJR indicator from Scopus data. The journal IF, first conceived in 1955 by Eugene Garfield, the founder of the Institute for Scientific Information (ISI), has been extensively used in past decades as an index of quality of scientific journals (Garfield, E. 2006) and is based on citation analysis (Garfield, E. 1972). ISI publishes JCR in every year which contains impact factor of journals indexed in Web of Science. Elsevier's Scopus, which became available in 2004, has been considered a competitor to Web of Science because of its citation tracking capabilities (Bakkalbasi et al. 2006). Spanish Universities developed the SJR indicator and lists the ranked journals indexed in Scopus according to their impact. The SJR is based on the transfer of prestige from a journal to another; such prestige is transferred through the references that a journal do to the rest of the journals and to itself.


The main objective of this study was to identify database coverage of Indian journals in Scopus and Web of Science and to compare the impact factors Indian journals in JCR and SJR.


A list of Indian journals was compiled from online access to Web of Science and Scopus. The lists of Indian origin journals indexed in Web of Science and SCOPUS were prepared separately. Database coverage of Indian Journals in Web of Science was identified and matched with JCR 2008 to assess their impact factors...
