What and why?

Terminology

Author's version

'Author's version' refers to the final version of the manuscript after peer review, but before the final layout by the publisher. This version is also known as the 'post-reviewed preprint', 'accepted version', 'postprint', 'post-refereed print', or 'author's accepted manuscript (AAM)'.

Hybrid journal

In contrast to fully Open Access journals, hybrid journals are subscription-based but offer authors the option to publish their individual article in Open Access by paying an 'article processing charge' (APC). The articles published via this route are freely accessible to readers, but the journal itself is still published behind a paywall. This practice is referred to as 'double dipping' because the journal makes double profits: on one hand, the author pays a publication fee to make their article Open Access, and on the other hand, the reader/library pays a subscription fee to access the other articles in the same journal.

Preprint | postprint

  • The preprint is the manuscript that has not yet undergone peer review and has not been accepted for publication.
  • The postprint is the peer-reviewed manuscript that has been accepted for publication (usually a Word or LaTeX file). It has the same content as the published version, but without the final formatting done by the publisher.

Plan S

What is Plan S?

Plan S was launched in September 2018 by cOAlition S, a consortium of national research institutions and funders from twelve European countries, with the main goal of accelerating the transition to immediate Open Access. All researchers who have been funded since 2021 by an organisation supporting Plan S are required to make the publications resulting from their Plan S-funded research immediately available in Open Access (without embargo) and under a free license. Learn more about the principles of Plan S on the cOAlition S website.

Why was Plan S launched?

The idea behind Plan S is that optimal scientific progress can only be achieved when research results are openly available to the community, allowing them to be scrutinized and reviewed by other scientists and enabling maximum building upon previous research. The subscription-based model of scientific publishing, where a significant portion of publications is behind paywalls, is no longer sustainable and poses a fundamental barrier to science and to society at large.

To which types of publications does Plan S apply? 

All peer-reviewed scientific publications of any type fall under Plan S. However, the guidelines for monographs and book chapters have not yet been specified. Additionally, cOAlition S encourages making research data and other research outputs "as open as possible and as closed as necessary" publicly available.

Who does Plan S apply to?

Plan S is applicable to all researchers funded by organisations supporting Plan S since 2021. It does not yet apply to the FWO (Research Foundation Flanders) and ERC (European Research Council), but it does apply to Horizon Europe (pdf, 912 KB).

How can I comply with the Plan S requirements?

At the moment, Plan S applies only to journal articles. If these articles arise from research funded after January 1, 2021, by a research funder that supports Plan S, they must be made immediately available in Open Access and under a free license (without embargo). This can be achieved in several ways:

  • Consult the journal Checker Tool, a web-based instrument that provides researchers with advice on how to comply with the Plan S-aligned Open Access policies of their funders when they wish to publish in their chosen journal. If you cannot find the journal you wish to publish in via the Journal Checker Tool, consider one of the options listed below.
  • Publish in an Open Access journal or through an Open Access platform listed in the Directory of Open Access Journals (DOAJ).
  • Publish in a subscription-based journal and deposit at least the author's version (or the published version if possible) of your publication in an Open Access repository that is aligned with Plan S (such as the UHasselt Document Server), without embargo and with the mention of a free license. Since most publishers impose embargoes by default, you can use the rights retention strategy proposed by cOAlition S to override this. Specifically, follow these steps:
    • Add the following text to the cover page or acknowledgements section of your author's version before submitting it to your chosen journal: "This research was funded, in whole or in part, by [Organisation Name, Grant #]. A CC BY or equivalent license is applied to [the AAM / the VoR] arising from this submission, in accordance with the grant’s open access conditions." The AAM refers to the Author Accepted Manuscript, which is the author's version of your publication. VoR stands for Version of Record, which is the final published version of your article.
    • Once your article is accepted for publication, deposit your author's version in a public repository such as the UHasselt Document Server.
    • If your publisher does not agree with the above approach, contact your funder for further guidance.
  • Publish in a hybrid journal that falls under a transformative agreement. With this agreement, the publisher commits to transforming the journal into a fully Open Access journal in the near future.

Different routes

If you want to publish your research in Open Access, you have several options or 'routes' to choose from, including the 'green road' (publishing in a subscription-based journal but depositing the author's version of your article in the Document Server) and the 'golden road' (publishing your work immediately in Open Access on the publisher's website, making the published version freely accessible to the public).

UHasselt has developed an Open Access policy based on the green route.

The green road

You publish your work behind a paywall (in a journal with a subscription model), but after publication, you deposit the author's version of your article in a free online database, such as Document Server, the institutional repository of UHasselt, making your article freely available to the rest of the world. Of course, this is done within the limits allowed by copyright.

For journal articles, the University Library applies the Belgian Open Access legislation by default. This law grants you the right to make the author's version of your journal articles freely available in Open Access through our repository, provided they meet certain conditions, after an embargo period of up to 12 months (for humanities and social sciences) or 6 months (for all other sciences). You can also apply the law retroactively, which means that you can even convert previously published articles into Open Access, thereby increasing the accessibility of your research.

What is interesting is that the Belgian Open Access law always supersedes the embargo provisions set by your publisher. This makes it easier for you to comply with any open access requirements imposed by your funder. The full law can be found in Belgisch Staatsblad (Belgian Official Gazette), 2018-09-05, p. 68691, Art. 29 (pdf, 2.6 MB).

The golden road

You publish your work immediately in Open Access on the publisher's website, making the published version freely accessible to the public. The reader does not have to pay to access your publication.

This route is typically not free. The publication costs, known as 'article processing charges' (APCs), are paid by the author or their institution. The publication fee ranges from 0 to 2,500 euros, and in exceptional cases, amounts of up to 5,000 euros may be charged. UHasselt does not provide a fund to cover these APCs, nor are there deals with publishers in Flanders regarding APC funding. However, before you consider paying the costs yourself, it is worth checking whether your research funder can partially or fully cover them.

Please note: Originally, the gold route was exclusively offered by 'full' Open Access journals, but nowadays, there are also more and more 'hybrid journals', traditional journals that operate under a subscription model but also offer authors the option to make their specific article available in Open Access for a fee (APC). This practice is also known as 'double-dipping' as the publisher benefits twice: once from the subscription fees and again from the APCs. The APC costs are in addition to the normal subscription price of the journal. For this reason, UHasselt advises against publishing in Open Access in hybrid journals.

OA policy @UHasselt

Hasselt University supports an Open Access vision based on the 'green road'. This means that every UHasselt author who publishes peer-reviewed journal articles and/or peer-reviewed proceedings papers in a paid journal or proceedings book, commits herself or himself to include the author's versions of these publications in the Document Server (i.e. the institutional repository of Hasselt University).

By the author's version we mean the last version of the text after peer review, but before the final layout of the publisher. This version is also known as the 'post-reviewed preprint', 'accepted version', 'postprint', 'post-refereed print' or 'author's accepted manuscript (AAM)'. This author's version can be made freely available, whether or not after an embargo period. In this regard, the Belgian Open Access legislation is invoked for journal articles, and the publisher's copyright policy is taken into account for proceedings papers.

To be clear:

  • The University Library also aims to include the published version in the Document Server. It is only made accessible within Hasselt University via the closed intranet.
  • If the publisher allows the published version to be made public entirely (eg. if you have published in a gold Open Access journal), only the published version is uploaded and made available to everyone; uploading the author's version is, of course, superfluous in that case.

What is expected of each UHasselt author?

All UHasselt authors are expected to upload the author’s version of their peer-reviewed publications from subscription journals and proceedings in the repository of Hasselt University (Document Server).

We recommend executing the upload of the publication concurrent to its official publication by the publisher. If desired, this task can be outsourced to a colleague or secretarial assistant.

The University Library checks the embargo provisions of the Belgian Open Access legislation (for journal articles)/the publisher (for proceedings papers) for each uploaded text and adjusts the access on the Document Server accordingly. This results in three options:

  • open access: the full text is freely available to everyone, including external parties;
  • restricted access: although an embargo has been imposed on the full text, it can nevertheless be consulted by UHasselt staff and UHasselt students once they have logged in;
  • closed access: an embargo has been imposed on the full text and it cannot be consulted by anyone; if required, an embargo can even be imposed on the metadata.

To be clear:

  • The UHasselt author will receive an email confirming the successful inclusion of her/his work in the repository. Should there be any missing details, the University Library will contact the UHasselt author.
  • Publications that are recorded in the Web of Science are checked by the University Library once they have been included in the Web of Science, and, if necessary, uploaded to the Document Server, after which the researcher is asked for the author’s version.
  • UHasselt authors are personally responsible for the correctness and completeness of their publications list.
  • For journal articles, the University Library applies the Belgian Open Access legislation by default, and for proceedings papers, the copyright policy of the publisher is taken into account. It is the responsibility of the University Library to correctly apply this information. However, if specific agreements have been made between the UHasselt author and the publisher about making the text available via the Internet or if certain intellectual rights must be taken into account, the UHasselt author must report this to the University Library.

Follow-up

After deposit, any adjustments or corrections to publications can be passed on to the University Library, which bears ultimate responsibility for this. In the event of any discussion about publication categories, the Research Coordination Office will be contacted, which will also deal with all other disputes.

Why does Hasselt University opt for the 'green road'?

 Choosing the ‘green road’ option has a lot of advantages:

  • many research funds mandate making publications available in Open Access, and by depositing the author’s version in the Document Server, you comply with this mandate (especially if the funder can agree to a short embargo period);
  • European policy wants to introduce Open Access as a publication standard;
  • maximum archiving (long-term storage) of the own publication output, so that current and future students and researchers have access to UHasselt research;
  • no barriers when publishing; free choice of journal is guaranteed;
  • much cheaper than the golden road;
  • no risk of "double dipping" wherein the publishers retain both the fee for the Open Access publication of an article ('APC') plus the regular subscription price for the journal;
  • publication lists can be exported and integrated into websites;
  • link with various other UHasselt applications to avoid double entry.

 

Is OA an obligation?

On the one hand, more and more funders are imposing obligations on making publications available in Open Access, either directly via the publisher — often by paying an 'article processing charge' (APC) — or by submitting the author's version of your article in a free online database such as the Document Server (i.e. the institutional repository of Hasselt University).

On the other hand - in accordance with the UHasselt Open Access policy - all UHasselt authors are expected to upload the author's version of their peer-reviewed publications from subscription journals and proceedings in the repository of Hasselt University (Document Server).

The table below provides an overview of the Open Access requirements of several major research funders. For the most current and comprehensive information, we recommend always consulting the official website of the respective funder. You can also use the Open Policy Finder to look up your funder's Open Access policy, but please note that this source may not always be fully up to date.

Horizon Europe: key Open Access requirements

Are you involved in a Horizon Europe project? If so, you’re required to provide Open Access to all peer-reviewed scientific publications that result from your research. This aligns with the principles of Plan S, which promotes full and immediate Open Access for publicly funded research.

Here is a quick overview of the main obligations under Horizon Europe:

Publication

  • Peer-reviewed publications must be made openly accessible immediately upon publication—no embargo allowed—via a trusted repository, such as:
    • The UHasselt Document Server
    • A subject-specific repository (e.g. arXiv, Europe PMC)
    • Zenodo, the OpenAIRE platform hosted by CERN

      Important: The following platforms do not qualify as repositories under Horizon Europe:
      • Your personal website
      • Cloud storage services (e.g. Dropbox, Google Drive)
      • Academic social networks (e.g. ResearchGate, Academia.edu)
  • Upload a machine-readable version of your publication, either the Version of Record (VoR) or the Accepted Author Manuscript (AAM/postprint).
  • Apply a Creative Commons license:
    • For journal articles and book chapters, a CC BY license is mandatory.
    • For books or longer texts, CC BY-NC or CC BY-ND is also permitted.

Verifiability

  • Through the repository, you must also provide information about the research data, software, or other resources needed to verify the findings presented in your publication.

Author’s rights 

  • You and your co-authors must retain sufficient author’s rights to ensure compliance with the Open Access requirements.

Metadata

  • Metadata must be openly available under a CC0 licence and comply with the FAIR principles.
  • Include key details such as: authors, title, date, publication venue, Horizon Europe project information, licence, and persistent identifiers (e.g. DOI).

How to retain your author’s rights

To comply with the Horizon Europe requirements, you must retain sufficient author’s rights as an author. There are two main ways to do this:

  1. Sign a publishing or copyright transfer agreement that allows you to deposit either the Author Accepted Manuscript (AAM) or the published version in a trusted repository, and to make it immediately available in Open Access, without any embargo.

    To help you find journals that meet Horizon Europe’s Open Access requirements, you can use the following tools:
    • Journal Checker Tool
      Check whether a specific journal allows publishing in line with Horizon Europe’s Open Access rules.
    • Directory of Open Access Journals (DOAJ)
      A comprehensive directory of fully Open Access journals that publish under a CC BY licence or an equivalent open licence.
    • Open Research Europe
      The European Commission’s own Open Access publishing platform. Publishing here automatically fulfills Horizon Europe’s Open Access requirements.
  2. Use the Rights Retention Strategy from cOAlition S. This means that when submitting your manuscript, you include the following statement—either on the cover page or in the acknowledgements—to indicate that your publication falls under Horizon Europe and requires a CC BY licence:

     “This work was funded by the European Union under the Horizon Europe grant [grant number]. As set out in the Grant Agreement, beneficiaries must ensure that at the latest at the time of publication, open access is provided via a trusted repository to the published version or the final peer-reviewed manuscript under a CC BY or equivalent license.”

    If your publisher does not agree with this approach, please contact your funder or consider choosing a different publication channel.

Are publication costs reimbursed?

  • Only APCs for fully Open Access journals or platforms are reimbursed. Costs for hybrid journals (subscription + OA option) are therefore not eligible.
  • If you expect publication costs, make sure to include Open Access expenses in your project budget.
  • Open Access doesn’t have to be expensive: you can achieve Open Access at no cost through repositories or free OA journals.
  • Horizon Europe projects can also publish for free via Open Research Europe, the EC’s platform that meets all Open Access requirements.

FWO: key Open Access requirements

Based on the principle that research financed with public funds should be available to the public, the FWO requires that "research results are published in Open Access" (General Regulations FWO, Article 2, Paragraph 2). However, this does not automatically mean that you always have to pay for Open Access publication. The key points are:

  • The obligation applies to peer-reviewed journal articles (A1) that are (partially) the result of FWO funding.
  • There are two options to comply with this obligation:
    1. Publish in an Open Access journal (possibly with an APC).
    2. Use the “green road”: upload the author accepted manuscript (AAM) to the UHasselt Document Server.
  • The FWO allows for an embargo period of up to 12 months.
  • The author version may be freely shared under the Belgian Open Access law:
    • Max. 12 months embargo for the humanities and social sciences.
    • Max. 6 months for the other sciences.
  • If you choose to publish in an Open Access journal, any Article Processing Charges (APCs) can be paid using your FWO project’s operational funds or, for example, via the University Foundation. This applies both to peer-reviewed journal articles and to other publication types such as books.

    Please note: Hasselt University does not provide central funding for APCs, nor are there deals in place in Flanders with publishers regarding APC funding (with a few small exceptions).

Choosing an OA journal

To find a suitable Open Access journal for publishing your research, it's wise to start by following general guidelines for selecting a high-quality journal.

A useful resource to consult is the Directory of Open Access Journals (DOAJ), a comprehensive index of high-quality Open Access journals that apply peer review. By searching by subject in the DOAJ, you can find journals relevant to your field and meeting rigorous quality standards. Furthermore, by choosing an Open Access journal, you also contribute to promoting open and accessible scientific communication.

Recognizing predatory journals

Researchers who are not so familiar with Open Access sometimes worry about the quality of Open Access journals. These doubts are often fueled by the phenomenon of 'predatory journals.' However, it's important to emphasize that the majority of Open Access journals do not engage in 'predatory' practices.

Predatory journals are journals that publish articles in Open Access and charge high publishing costs or APCs, without, however, organizing decent editorial services and peer review. In other words, they take advantage of the Open Access model solely to make money. The articles concerned are not necessarily worthless; they can contain perfectly reliable research that has unfortunately been published in a predatory journal (the publications, therefore, do not count for funding and for career evaluation).

Here are some important tips to recognize such dubious journals. To be completely sure, however, it is also advisable to consult the page with more general rules of thumb in which the tips below are included.

If you still have doubts despite following the tips above, please contact the University Library (eline.schoeters@uhasselt.be | +3211268122) or choose another journal.

Frequently Asked Questions

FAQ | General

Are there any costs associated with Open Access publishing?

The publisher often charges publication costs or so-called 'article processing charges' (APCs) for the Open Access publishing of your article or book. We then speak of Gold Open Access.

Please note: Hasselt University does not provide a fund with which these APCs can be paid, nor are there any deals in Flanders with publishers regarding the financing of APCs. Before you pay the costs yourself, it is, however, worth checking whether your research funder cannot (partially) accommodate them.

To circumvent the sometimes high APCs, you can choose to publish in a journal with a subscription model, and before or after publication, include the author's version of your article in the Document Server (i.e. the institutional repository of Hasselt University), after which it becomes freely available to the rest of the world, whether or not after an embargo period. In this case, we speak of Green Open Access. You do not have to worry about copyright, because Hasselt University always checks which embargo provisions apply. All of this is part of Hasselt University's Open Access policy.

You want to publish in Open Access: where can you find reliable publication channels?

Where can you check the embargo provisions of a publisher or journal?

A handy tool for this is Open Policy Finder

What are your options if the publisher of your publication imposes a longer embargo period than allowed by your funder?

The Belgian Open Access legislation is a possible solution. This law gives you the right to make the author's version of your journal articles - provided they meet certain conditions - available for free in Open Access via our repository, and this after an embargo period of maximum 12 (for the human and social sciences) or 6 (for all other sciences) months. 

Interestingly, this law always overrules your publisher's embargo provisions. This makes it easier for you to comply with any open access requirements imposed by your funder. The full law can be found in Belgisch Staatsblad (Belgian Official Gazette), 2018-09-05, p. 68691, Art. 29 (pdf, 2.6 MB).

FAQ | OA policy @UHasselt

What is the UHasselt policy regarding 'gold Open Access'? Can you contact UHasselt to reimburse APCs (article processing charges)?

More information about this can be found here.

Can UHasselt authors still publish in any journal?

Of course. UHasselt authors are free to decide in which journal they wish to publish their research results. All that is expected of them is to upload the final author's version of their peer-reviewed publications to the institutional repository (Document Server).

How can you find out whether your journal has a policy compliant with depositing your manuscript in an institutional repository?

To avoid any misunderstanding, the University Library checks the embargo provisions of the Belgian Open Access legislation (for journal articles)/the publisher (for proceedings papers) for every uploaded text. Access to the author's version in the Document Server is adjusted accordingly. So this is actually something you don't need to worry about.

Some authors fear copyright problems if they upload their work to repositories. This is incorrect. Even if you as an author do not have the exploitation rights to your work, many traditional publishers still allow self-archiving of the author's version. In any case, the University Library checks the embargo provisions of the Belgian Open Access legislation (for journal articles)/the publisher (for proceedings papers) for every uploaded text and takes into account comments about the protection of intellectual rights. Access to the author's version in the Document Server will be adjusted accordingly.

What if there is no author’s version available?

If you really cannot upload an author's version, please indicate this in the 'Comments' field in the Document Server submission form.

What kind of support does the University Library offer?

  • After the official publication by the publisher, you upload your author's version into the Document Server. Only a limited set of metadata has to be entered.
  • The University Library carries out a quality check on this data and supplements it with data from the uploaded author's version and academic databases. The University Library also tries to include the published version in the Document Server.
  • You will receive an email confirming the successful inclusion of your work in the repository. Should there be any missing details, the University Library will contact you.
  • As in the past, the University Library will continue to screen UHasselt publications that are recorded in the Web of Science. If necessary, those publications are still entered in the Document Server, after which the author's version is requested.
  • The University Library checks the embargo provisions of the Belgian Open Access legislation (for journal articles)/the publisher (for proceedings papers) for every uploaded text and takes into account comments about the protection of intellectual rights. Access to the author's version in the Document Server will be adjusted accordingly.
