Journal citation identity, journal citation image and internationalisation: Methods for journal evaluation

Summary Journal Citation Identity, Journal Citation Image, and Internationalisation are methods for journal evaluation used for an analysis of the Journal of Documentation(JDOC) which is compared to JASIS(T) and the Journal of Information Science(JIS). The set of analyses contributes to portrait a journal and gives a multifaceted picture. For instance, the Journal Citation Image by the New Journal Diffusion Factor tells that JDOC reaches farther out into the scientific community than the JASIS(T) and JIS. Comparing New Journal Diffusion Factor and Journal Impact Factor illustrates how new information has been added by the new indicator. Furthermore, JDOC is characterised by a higher rate of journal diversity in the references and has a lower number of scientific publications. JDOC authors and citers are affiliated Western European institutions at an increasing rate.
