It is reported that CiteScore is a new journal evaluation system launched by Elsevier in December 2016. CiteScore2021 was obtained by dividing the citations of papers, reviews, conference papers, book chapters and data papers between 2018 and 2021 with the total number of papers published between 2018 and 2021, covering a period as long as 4 years. As a result, it provides a more convincing picture of the influence of journals. CiteScoreTracker 2022 will be updated on a monthly basis till the next year of CiteScore calculation.
