(Toronto, 19.06.2009) On June 19th, 2008, Thomson Reuters released their 2008 Journal Citation Reports, reporting journal impact factors for the worlds' most important scholarly journals.
With an excellent impact factor of 3.6 (up from last years 3.0) JMIR is now officially the leading, #1 ranked publication (out of 20 journals) in the medical informatics category. JMIR was ranked #2 in 2006 and 2007, with an impact factor almost equal to the Journal of the Medical Informatics Association (JAMIA). In 2008, JAMIA (IF 2008: 3.4) has now been overtaken by JMIR.
About the Journal Impact Factor. The Journal Impact Factor is published in the Journal Citation Report (JCR), a product of Thomson Reuters ISI (Institute for Scientific Information). JCR provides quantitative tools for evaluating journals. The impact factor is one of these; it is a measure of the frequency with which the "average article" in a journal has been cited in a given period of time. The impact factor for a journal is calculated based on a three-year period, and can be considered to be the average number of times published papers are cited one or two years after publication. The 2008 Journal Impact Factor (published in June 2009) takes into account citations that occurred in 2008 (n=219), to JMIR articles published in 2006/2007 (n=61).
