    Research Integrity

    Publication Ethics

    Utrecht University Library Open Access Journals (Uopen Journals) is not the owner of the journals but acts as a service provider. Uopen Journals stands for editorial and peer review procedures, which are of the highest standard and carried out both rigorously and transparently.

    Utrecht University Library Open Access Journals is committed to upholding the highest standards of quality and integrity in scholarly publishing. Publishers and editors will take reasonable steps to identify and prevent the publication of papers where research misconduct has occurred, including plagiarism, citation manipulation, and data falsification/fabrication, among others. In no case shall our journals or their editors encourage such misconduct, or knowingly allow such misconduct to take place.

    The journals in the Uopen Journals portfolio adhere to the best practices in the ethics of scholarly publishing stated in the COPE (Committee on Publication Ethics) Code of Conduct and Best Practice Guidelines for all parties involved: Authors, Editors, Reviewers, and the Publisher.

    Our journals undertake to publish all corrections, clarifications, retractions and apologies as soon as possible if and when they are required.

    Rigorous Peer Review

    In general all articles are sent for external peer review prior to an editorial decision on whether to accept or reject a submission. Reviewing should be conducted by independent peers and editorial boards should not act as main reviewers. Publications of a commentary or opinion nature may not be sent for external peer review but will include extensive editorial review and revisions.

    Competing Interests

    Uopen Journals is committed to transparent and bias-free research. To ensure a reliable and open publication process, all authors, reviewers and editors are required to declare any interests that could appear to compromise, influence or be in conflict with the validity of the publication. This process is designed to reinforce the readers' trust in the research data.

    Open Licenses

    All Open Journals’ content is released using a Creative Commons license. Our default and preferred licence is CC-BY. We believe this licence meets the requirements for true open access for journals. We strongly prefer CC0 for open research data.

    Indexing & DOI

    Uopen Journals ensures that all published content is indexed with CrossRef and assigned a Digital Object Identifier (DOI). This means that each reference is available so that the publishing community can track citations.

    All of our article metadata is openly available for harvesting by indexing services via the OAI-PMH metadata protocol. We assist and advise our journal editors in finding suitable (OA) indexing services (e.g. DOAJ) and can provide advice to editors on how to improve the chances of application to high impact index services.


    As member of CLOCKSS (Controlled Lots of Copies Keep Stuff Safe) our content is regularly archived with many of the world's leading research libraries. The CLOCKSS archive ensures that all Uopen Journals content will always be made available as open access, in any eventuality. We fully support and encourage author self-archiving of all content (sometimes termed 'green' open access). We register all of our journals with SHERPA/RoMEO to ensure that the license terms and self-archiving policies of the journals are clear.

    No Lock-in

    Uopen Journals uses open, non-proprietary standards for all of its content, meaning that it can be easily transferred to archives and other publishers. We endorse and adhere to the UKSG Transfer Code of Practice, which ensures that when a journal transfers between publishers, librarians, editors, and other publishers are informed and treated fairly.
