Open Access, Free Access, and Article Archiving

Open Access, Free Access, and Article Archiving

The AACR journals provide several mechanisms for authors to provide open and free access to their published articles. All articles published in AACR journals are made free (open) to read no later than 12 months after publication.

Open Access

Authors may opt to publish their research under an open access license in any of the AACR hybrid journals. The hybrid AACR journals include: Blood Cancer Discovery; Cancer Discovery; Cancer Epidemiology, Biomarkers & Prevention; Cancer Research; Cancer Immunology Research; Cancer Prevention Research; Clinical Cancer Research; Molecular Cancer Research; and Molecular Cancer Therapeutics. Selection of open access in any one of these journals permits immediate access to the typeset version of record published in the online journal. Details on open access fees are available in the Publication Fees section.

Publishing your research as open access in any of these titles will be covered by a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 (CC BY-NC-ND) license. If mandated by an author’s funding institution, a Creative Commons Attribution 4.0 (CC BY) license may be used. For information about different Creative Commons licenses, please see

In October 2021, the AACR launched its first exclusively open access journal, Cancer Research Communications. All manuscripts accepted for publication in this journal are published under a Creative Commons Attribution 4.0 (CC BY) license.



Important: The AuthorChoice option was discontinued effective May 6, 2021. Authors who wish to make their manuscript immediately freely available online, may instead make use of our new open access option (see above).

For many years, the AACR journals provided an option for authors to pay an AuthorChoice fee to make their accepted articles freely available online at the journal website immediately upon publication. This included OnlineFirst and final typeset article versions. AuthorChoice articles were not published under an open access license and were therefore generally ineligible for funder reimbursement of the AuthorChoice publication fee.


Free Access and Article Archiving

All published articles in AACR journals under standard copyright are made free (open) to anyone to read no more than 12 months after the original online publication date. In addition, the AACR provides many countries in the developing world with immediate free access to all AACR journals through the HINARI program. Select content will sometimes be made freely available immediately upon publication.

The AACR can assist authors in meeting those funders' archiving mandates that mandate deposition in PubMed Central (PMC) or Europe PMC within at least 6 months of publication. Authors of articles published in AACR journals can elect after Provisional Acceptance to have the AACR deposit their accepted manuscripts to PMC or Europe PMC, thereby meeting the archiving and release date requirements of the following funding agencies and others:

  • National Institutes of Health
  • Cancer Research UK
  • Medical Research Council

When submitting a revised version of their manuscript after Provisional Acceptance, the corresponding author is asked to indicate whether the accepted version of their manuscript should be deposited in PMC or Europe PMC on their behalf, or if they will instead deposit the accepted version themselves. Authors are NOT asked to provide funding information or choose a deposition option at initial submission.

If the author chooses to have the AACR deposit the manuscript for them, the accepted version of the manuscript will be uploaded to the repository upon acceptance, with a release date of 6 months after print publication. Authors will be contacted by the repository for approval of the submission.

Please note that the article PMCID number is assigned and provided by NIHMS and Europe PMC and that the AACR journals are unable to assign or provide these numbers to authors. Authors who have questions about their PMCID number should contact the corresponding repository directly at or

It is important to note that, although the AACR will make PMC and Europe PMC deposits for authors upon request at the time of manuscript acceptance, it is the author's responsibility to follow up with the repository to ensure that the content is received and released within the funder's specified timeframe. Authors whose funders require deposition and release less than 6 months from the date of publication (for example authors with a cOAlition S funder) must make the deposit arrangements in the appropriate repository themselves, with the appropriate release date no earlier than the date of publication in the journal. For information about AACR policies on institutional repositories and preprint servers, please see Online Postings.

AACR uses CLOCKSS to archive all published content of the journals at a separate location from the primary journal archive. This ensures that all materials are archived and accessible in perpetuity.
