DOAJ's definition of Open Access

DOAJ only accepts Open Access journals.

  • DOAJ defines Open Access journals as journals in which the copyright holder of an academic work transfers the right of use to others through an open license (Creative Commons or equivalent - for an explanation, see the section 'Licensing' below). The open license allows immediate free access to the work and allows any user to read, download, copy, distribute, print, search or link to full-text versions of articles, to 'crawl' them in connection with online indexing, translate them into data in software or use them in any lawful context.
  • The journal must present an Open Access declaration, which shows that DOAJ's definition of Open Access is met.
  • Full-text versions of all content must be available for free as Open Access without delay.
  • There must be no embargo periods.
  • It is not accepted that users must register in order to read content.
  • An amount is allowed to be charged for the print version of a journal.

Journal websites

  • The journal must have its own dedicated URL and website and be accessible from all locations.
  • The website must be easy to understand and easy to navigate.
  • The journal should adhere to the guidelines outlined in the Principles of Transparency and Best Practice in Scholarly Publishing.
  • Each article must be available as an individual full-text article.
  • There must be one unique URL per article.
  • The format must at least be HTML or PDF.
  • Journals that contain intrusive marketing will not be accepted for indexing.
  • DOAJ does not allow the use of Impact Factors. However, DOAJ acknowledges that the only official Impact Factor is the one created by Clarivate. Journals may not display Impact Factors or similar forms of 'ranking' from any other services.
  • The website does not have to be in English. If the website is available in several different languages, all information must be the same in all languages.

The following information about the journal must be available online and easily accessible from the journal's website:

  • Open Access Policy
  • Purpose and focus
  • Editorial staff (including institutional affiliation for all members)
  • Author Guide
  • Editing process (peer-review)
  • License Terms
  • Copyright Terms

Author fees

  • If a journal has no fees or charges, this must also be stated.
  • The information must include any fees or charges that an author may be charged from submission to publication, including article processing charge (APC).

Contact information:

  • The contact information must include a correct name of a contact person and the journal's e-mail address.
  • The country listed in the DOAJ application and on the journal's website must be the country where the publisher is registered and carries out its business activities.


  • A journal must have at least one International Standard Serial Number (ISSN) registered and verified on
  • The ISSN(s) must appear on the website.
  • The name of the journal in the application to DOAJ and on the journal's website must be the same as that listed on

Quality control

A journal must have an editor and an editorial team.

  • The editorial team must appear on the website.
  • The names and affiliates of all editors and members of the editorial team must appear on the website.
  • If the journal is run by a student organisation, it must have an 'advisory board', of which at least two members have a PhD or equivalent degree.
  • The journal's editorial team should consist of at least five people. It is recommended that not all members come from the same institution.
  • All articles must undergo a peer review before publication.
  • The method of peer review (eg 'blind' or 'double blind' etc.) and the details associated with it must be clearly stated on the website.
  • It is recommended to use a service that can identify and prevent plagiarism, but this is not a requirement.
  • The number of articles written by members of the editorial team should be minimised.
  • The proportion of publications in which at least one of the authors is an editor, a member of the editorial team or a reviewer may not exceed 20% of the content of the journal's last two editions.


  • The license terms for the use and reuse of the published content must be clearly stated on the journal's website.
  • DOAJ recommends the use of Creative Commons licenses for this purpose (see below).
  • If Creative Commons licensing is not used, similar terms and conditions should apply. Explanation of such conditions should be carried out with extra care.
  • It is recommended that licensing information be provided by or embedded in full-text articles, but this is not a requirement for indexing in DOAJ.

In the case of Open Access publishing, Creative Commons licenses are a key copyright tool. With a Creative Commons license (CC license), the author retains the copyright to his work, but can then can tailor the copyright as needed, thereby giving the user of a work a number of freedoms in relation to applicable copyright. Creative Commons covers the area between full rights reserved ('all rights reserved'), partial copyright ('some rights reserved') and a total waiver of rights to the work ('public domain').


  • Copyright terms that apply to the published content must be clearly stated and stand apart from similar terms that apply to the website, for example.
  • Copyright terms must not conflict with the license terms or conditions of Open Access policy.
  • Full rights reserved ('All rights reserved') are never suitable for Open Access content.

There may be special rules or exceptions for certain types of journals. These can be viewed on the DOAJ website.
