This major update entails the inclusion, for the first time, of complete citation and publication data from Scopus 2008 dataset as well as the availability, on the SJR website, of indicators for journals and countries for that year. In terms of coverage, the update implies the inclusion of new titles coming from the recent Scopus inclusion of ERIH's Art and Humanities. In addition, a new journal assessment feature was added to the website, consisting of the inclusion of Journal's SJR indicator Quartiles. We describe below some important facts about the update.
