About PNAS
PNAS is one of the world's most-cited and comprehensive multidisciplinary scientific journals, publishing more than 3,500 research papers annually.
The Proceedings of the National Academy of Sciences (PNAS), the official journal of the National Academy of Sciences (NAS), is an authoritative source of high-impact, original research that broadly spans the biological, physical, and social sciences. The journal is global in scope and submission is open to all researchers worldwide.
PNAS was established in 1914 in honor of the semicentennial anniversary of the National Academy of Sciences. Since then, we have worked to publish only the highest quality scientific research and to make that research accessible to a broad audience. In addition, PNAS publishes science news, Commentaries, Perspectives, Colloquium Papers, podcasts, and profiles of NAS members.
In 1995, PNAS began accepting Direct Submissions from researchers without an NAS affiliation. While we retain strong ties with the NAS, whose members oversee the journal’s rigorous three-tier peer review process, we now receive more than 17,000 Direct Submissions each year. Direct Submissions account for more than 75% of the research we publish.
PNAS is available by subscription, and all content is free after 6 months. Authors who choose the open access option can have their articles made available without cost to the reader immediately upon publication. More than 120 countries have free access to PNAS through our Equitable Access Initiatives.

Useful Features
Content portals and journal features provide fresh perspectives on science at a general level—features on trending topics, opinions, explanations of core scientific concepts, and exploration of science and culture—to advance understanding of all aspects of science.
Daily Publication
PNAS articles are published online directly into an open issue on a daily basis. First decisions are typically made within 21 days. The date of online release is the official date of publication. PNAS articles appear in an issue on publication. PNAS can offer publication in as little as 4–5 weeks after acceptance to authors who return their proofs quickly.
Relevant Science
The PNAS website launched in January 1997 and now receives over 15 million page views per month. The site contains PDFs of PNAS articles dating back to 1915, and the full text, figures, tables, equations, and references dating back to November 1996. PNAS makes all content free within 6 months of publication and immediately free in 124 lower-income countries. Authors who choose the PNAS open access option pay a surcharge to make their papers immediately free.

PNAS supports the following initiatives:
PNAS is an adopting organization of the Coalition for Diversity & Inclusion in Scholarly Communications (C4DISC).
PNAS deposits open references, funder information, publication licenses, and abstracts to CrossRef to help make research outputs easy to find, cite, link, and assess.
CrossMark is a CrossRef initiative to provide a standard way for readers to locate the authoritative version of a document. The CrossMark logo means that PNAS is committed to maintaining the content it publishes and to alerting readers to changes when they occur. Clicking on the CrossMark logo will provide the current status of a document and any additional publication record information.
PNAS participates in FundRef, a CrossRef initiative to provide a standard way of reporting funding for published research. To see if a PNAS paper has FundRef data, click on the CrossMark logo that appears with the paper, and select the Record tab.
ORCID provides a persistent digital identifier that distinguishes you from every other researcher and, through integration in research workflows such as manuscript and grant submission, supports automated linkages between you and your professional activities ensuring that your work is recognized. PNAS strongly encourages all authors to use their ORCID identifier when submitting papers. ORCID registration takes 30 seconds.
PNAS is a signatory to CHORUS, an initiative to give agencies and publishers a sustainable method for giving the public access to funded research.
The Initiative for Open Citations (I4OC) is a collaboration between scholarly publishers, researchers, and other interested parties to promote the unrestricted availability of scholarly citation data.
PNAS supports the Initiative for Open Abstracts (I4OA) and the call for unrestricted availability of abstracts to boost the discovery of research. Abstracts for PNAS articles are freely available and deposited with Crossref.
PNAS has been a member of the Committee on Publication Ethics (COPE) since 2008 (JM00047) and supports its core practices.
