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.

Journal ranking is widely used in academic circles in the evaluation of an academic journal's impact and quality. Journal rankings are intended to reflect the place of a journal within its field, the relative difficulty of being published in that journal, and the prestige associated with it.
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]
The following is a partial list of scientific journals. There are thousands of scientific journals in publication, and many more have been published at various points in the past. The list given here is far from exhaustive, only containing some of the most influential, currently publishing journals in each field.
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]
For instance, most papers in Nature (impact factor 38.1, 2016) were only cited 10 or 20 times during the reference year (see figure). Journals with a lower impact (e.g. PLOS ONE, impact factor 3.1) publish many papers that are cited 0 to 5 times but few highly cited articles. [21]
Adopting this view, the SJR indicator assigns different values to citations depending on the perceived prestige of the journals where they come from. However, studies of methodological quality and reliability have found that "reliability of published research works in several fields may be decreasing with increasing journal rank", [ 1 ...
