Recently released citation metrics from Clarivate and Scopus show ACS Publications journals continue to be the most cited in chemistry. The 2021 Web of Science™ Journal Citation Reports™ from Clarivate showed our journals have a median two-year impact factor of 5.097, up 14% from last year’s report. Data from Scopus showed the average ACS Publications journal has a CiteScore of 10.6. Both of these independent metrics reflect citations within a defined number of years for articles published within a defined period.
Total citations, meanwhile, increased by more than 550,000. This represents a more than 15% increase across the portfolio. Citations grew from the previous year for every ACS Publications journal, as the number of articles published also increased to 58,974, and usage among ACS’ readers grew to almost 170 million article downloads.
As a result, ACS journals were named the most cited or the most impactful in 10 categories, including five of the seven main chemistry categories: Chemistry, Analytical; Chemistry, Inorganic & Nuclear; Chemistry, Medicinal; Chemistry, Multidisciplinary; and Chemistry, Organic.
