About PNAS

PNAS is one of the world's most-cited and comprehensive multidisciplinary scientific journals, publishing more than 3,100 research papers annually. Established in 1914, PNAS publishes cutting-edge research, science news, Commentaries, Reviews, Perspectives, Colloquium Papers, and actions of the National Academy of Sciences. PNAS is available by subscription.

The journal's content spans the biological, physical, and social sciences and is global in scope. Nearly half of all accepted papers come from authors outside the United States.

PNAS strives to publish only the highest quality scientific research, and every paper undergoes rigorous peer review and approval by an NAS member before publication. Submissions are accepted from all researchers; authors do not need to have a connection to an NAS member to publish in PNAS.

New content portals and new 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.

PNAS articles publish daily online in PNAS Early Edition as soon as they are accepted and final author changes are made, and in weekly issues. First decisions are typically made within 21 days. The date of online release is the official date of publication. Papers publish online 1–4 weeks before they appear in an issue, and PNAS can offer publication in as little as 4–5 weeks after acceptance to authors who return their proofs quickly.

The PNAS website launched in January 1997 and now receives over 50 million hits per month. The site contains PDFs of all articles in PNAS dating back to 1915, and the full text, figures, tables, equations, and references dating back to November 1996. PNAS makes all content free just 6 months after publication and immediately free in more than 100 developing countries. Authors who choose the PNAS Open Access option pay a surcharge to make their papers immediately free.

PNAS is abstracted and/or indexed in, for example: CABI, Chemical Abstracts Service, Current Contents Connect, EBSCOhost, Elsevier Scopus, Gale, H. W. Wilson, Index Medicus, Journal Watch, JSTOR, OCLC, Ovid, Portico, ProQuest, Psychological Abstracts, PubMed, and SCI.

PNAS supports the following initiatives:



PNAS deposits all published content in CrossCheck, a multipublisher initiative started by CrossRef to help scientific publishers actively engage in efforts to prevent scholarly and professional plagiarism. CrossCheck is distinct from other plagiarism screening tools with its continuously growing database of current and archival scholarly literature. Wherever you see the "CrossCheck Depositor" logo, you can be reassured that the publisher whose content you are reading deposits into CrossCheck and is committed to publishing original research. To find out more about CrossCheck, visit http://www.danielhellerman.com/crosscheck/index.html.



CrossMark is a multipublisher initiative by the CrossRef Organization to provide a standard way for readers to locate the authoritative version of a document. By applying the CrossMark logo, PNAS is committed to maintaining the content it publishes and to alerting readers to changes if and when they occur. Clicking on the CrossMark logo will provide the current status of a document and may also provide additional publication record information about the document.



PNAS participates in FundRef, a multipublisher initiative started by CrossRef to provide a standard way of reporting funding for published research. The funding data are available through CrossRef for interested parties to analyze. 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 key research workflows such as manuscript and grant submission, supports automated linkages between you and your professional activities ensuring that your work is recognized. PNAS encourages authors to use their ORCID identifier when submitting papers. ORCID registration takes 30 seconds. For more information or to register, visit http://www.danielhellerman.com/.



CHORUS is an initiative started by non-profit CHOR, Inc., to give agencies and publishers a sustainable method for giving the general public access to funded research. PNAS is a signatory to CHORUS. For more information please visit the CHORUS website.



PNAS is a member of the Committee on Publication Ethics (COPE) since 2008 (JM00047) and subscribes to its principles.
