detailed tables showing
the number of times the articles in the journal were cited during the year by later articles in itself and other journals,
the number of citations made from articles published in the journal that year to it and other specific individual journals during each of the most recent ten years (the 20 journals most cited are included)
the number of times articles published in the journal during each of the most recent 10 years were cited by individual specific journals during the year (the twenty journals with the greatest number of citations are given)
There are separate editions for the sciences and the social sciences; the 2013 science edition includes 8,411 journals, and the 2012 social science edition contains 3,016 titles. The issue for each year is published the following year after the citations for the year have been published and the information processed.
The publication is available online (JCR on the Web), or in CD format (JCR on CD-ROM); it was originally published in print, with the detailed tables onmicrofiche.
In general, various universities, administrative centers and ministries in charge of higher education make their evaluations of university professors and other researchers on the number and quality of articles published in journals indexed in the JCR.[5]
In April 2020,Journal Citation Reports included a beta foropen access data, which usesUnpaywall data.[7] It officially left the beta phase with the release of the 2020 JCR in June 2020.[8][9]
Theimpact factor (IF) or journal impact factor (JIF) of anacademic journal is a type ofjournal ranking. Journals with higher impact factor values are considered more prestigious or important within their field. Impact factor is ascientometric index calculated byClarivate'sWeb of Science. The impact factor of a journal reflects the yearly mean number of articlecitations published in the last two years. While frequently used by universities and funding bodies to decide on promotion and research proposals, it has been criticised for distorting good scientific practices.[10][11][12]
