PNAS publishes ‘cutting-edge research’ and papers ‘must be of exceptional scientific importance.’ Contributions to PNAS are published under any of the following categories: Research reports, Letters, Front matter, Commentaries, Perspectives, and Colloquium papers; all but the first two are written only at the invitation of the editorial board.



Contributions must be submitted online through the PNAS Manuscript Submission System at New authors are required to register first. Detailed information on the preparation of manuscripts is available at


Each paper is assigned to a member of the PNAS Editorial Board from one of the 31 branches or disciplines defined by the journal. If a contribution passes this initial review, it is then taken over by one of the Member Editors, who may enlist specialist reviewers and evaluates their recommendations. The final decision is taken by the member of the editorial board. An infographic showing the process in detail is available at
