It provides information about academic journals in the natural and social sciences, including impact factors. JCR was originally published as a part of the Science Citation Index. Currently, the JCR, as a distinct service, is based on citations compiled from the Science Citation Index Expanded and the Social Sciences Citation Index. [48]
This is a list of open-access journals by field. The list contains notable journals which have a policy of full open access. It does not include delayed open access journals, hybrid open access journals, or related collections or indexing services.
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
The values for Nature journals lie well above the expected ca. 1:1 linear dependence because those journals contain a significant fraction of editorials. CiteScore was designed to compete with the two-year JCR impact factor, which is currently the most widely used journal metric. [7] [8] Their main differences are as follows: [9]
Within the scientific community, journal impact factors continue to play a large but controversial role in determining the kudos attached to a scientist's published research record. A list of over 14,000 journals was maintained by the ISI. The list included some 1,100 arts and humanities journals as well as scientific journals.
While these journals still did not receive an impact factor until the next year, they did contribute citations to the calculation of other journals' impact factors. [4] [5] In July 2022, Clarivate announced that journals in the ESCI obtain an impact factor effective from JCR Year 2022 first released in June 2023. [6]
