Journal Rankings
(The Journal Impact Factor, or JIF, denotes the average number of citations a paper of a given journal accrues within a two-year timespan, as calculated by Clarivate Analytics' database Web of Science; note that the journal coverage here at OOIR might deviate slightly from Web of Science's. The JIFs that used to have more than one decimal point are rounded here for copyright-related reasons.)
