It is the official journal of the National Academy of Sciences, published since 1915, and publishes original research, scientific reviews, commentaries, and letters. According to Journal Citation Reports, the journal has a 2020 impact factor of 11.205.[1] PNAS is the second most cited scientific journal, with more than 1.9 million cumulative citations from 2008 to 2018.[2] In the mass media, PNAS has been described variously as "prestigious",[3][4] "sedate",[5] "renowned",[6] and "high impact".[7]
