Open Access

‘Gold’ and ‘Green’ Open Access


See definitions at the bottom of the page.


Open Access articles attract far more attention than non-Open Access articles—in some cases more than 10-fold. Open Access articles are immediately available to a much broader audience, including the general public. This potentially results in a wider and greater impact and faster citation growth.


The Academic community promotes Open Access as the desired publication model for disseminating research results and in many situations today publication with Open Access is mandatory.


Inter-Research (IR) supports both the 'Gold' and 'Green' models of Open Access as follows:



‘Gold’ Open Access


IR offers Gold Open Access under the Creative Commons by Attribution License (CC-BY).


Article Processing Charges (APCs) for Open Access depend on article type and date of article submission, and range from € 650 to € 2500 for articles submitted on or after 1 November 2022, and from € 500 to € 2000 for articles submitted before 1 November 2022.


Feature Articles are published with Open Access at no cost to authors. Fee discounts or waivers are available for particular categories of hardship (for more information, refer to the individual journal links).


Full details of pricing for each journal are given in the following links:

Author self-archiving ('Green' Open Access)

(See definitions of terms at the bottom of the page)


‘Gold’ Open Access articles:


No restrictions. Authors are free to post the Preprint, Author Accepted Manuscript (AAM), and publisher’s Version of Record (VoR) of ‘Gold’ Open Access articles on any website or in any online repository.


‘Subscriber Access' articles:


Authors may self-archive 'Subscriber Access' articles as follows:


Author's personal website or personal page on his or her institutional website
Preprints may be posted at any time.
AAMs may be posted at any time after the article is accepted for publication by IR.
VoRs may be posted once the article becomes freely accessible from the IR website, 5 years after publication.


Preprint Servers
Preprints may be deposited on a Preprint Server at any time. Pay careful attention to the Open Access rules of that server; once deposited on the Preprint Server, it may be compulsory to publish the manuscript with Open Access if it is accepted for publication by Inter-Research.


Institutional Open Access Repository
Preprints may be deposited at any time.
AAMs may be deposited 12 months after publication. Authors who are mandated by their institutions to license—before the transfer of copyright to Inter-Research– the deposit of AAMs into their designated Institutional Repository within the 12 month embargo period must return the institution’s official “Addendum to Publication Agreement” (for each author affected) with the completed IR Manuscript Acceptance Form and obtain IR’s agreement to the Addendum.
VoRs may be deposited once the article becomes freely accessible from the IR website, 5 years after publication.


Plan S (articles deriving from research fully or partially funded by Plan S signatories)
Preprints may be deposited into an Open Access repository at any time.
AAMs may be assigned a CC-BY (or CC-BY-ND if agreed by the cOAlition S Organisation) or equivalent license, with the original copyright holders retaining their copyright in the AAM, and shared and/or deposited into an Open Access repository any time after publication of the publisher's VoR.
VoRs may be deposited once the article becomes freely accessible from the IR website, 5 years after publication.


UKRI, Wellcome, NIHR funded research
Inter-Research complies fully with the open access requirements of UKRI, Wellcome, and NIHR. Where required by their funder, authors retain the right to distribute their author accepted manuscript (AAM), such as via an institutional and/or subject repository (e.g. Europe PMC), under a Creative Commons Attribution 4.0 International (CC BY 4.0) licence for release no later than the date of first online publication.This takes precedence in cases of conflict with other Author self-archiving policies here.


PubMed (when mandated by funders)
Preprints may be deposited at any time.
AAMs may be deposited 6 months after publication.
VoRs may be posted once the article becomes freely accessible from the IR website, 5 years after publication.


Preprints may be deposited at any time.
AAMs may be deposited any time after publication, but with access limited to "supply on request" only.
VoRs may be posted once the article becomes freely accessible from the IR website , 5 years after publication.


In all cases, the article on a website or in the repository must have a link to its abstract page on the Inter-Research website, and cite the article doi.
