PNAS Online launched in January 1997 and now receives over 11.6 million hits per month. The site contains the full text, figures, tables, equations, and references of all articles in PNAS dating back to 1990.
PNAS articles are also published online before print in a feature called PNAS Early Edition as soon as they are accepted and final author changes are made. Release of articles became daily in June 2002. The date of online release is posted on the website and is the official date of publication. Papers are published online 1 to 5 weeks before they appear in print. PNAS can now offer publication in as little as 3.5 weeks after acceptance to authors who return their proofs quickly
