Several publishers have quota-based open access agreements. Once the agreed-upon number of open access articles has been published, the national quota is reached and the cost of publishing will no longer be covered centrally.
Based on current publication trends, we expect the following caps to be reached in 2025:
- LWW (Lippincott Williams & Wilkins) – reached on 4 September
- Taylor & Francis (T&F) – reached on 14 October
- Springer – reached on 23 October
- Oxford University Press (OUP) – reached on 30 October
- American Chemical Society (ACS) – reached on 13 November
Please take this into account when submitting to these publishers. After the cap is reached, authors may be faced with article processing charges (APCs) unless other arrangements are made. For more information about your options, please contact us at openaccess@umcg.nl
Alternative routes to open access
If your article is accepted after the cap has been reached, there are still ways to make your publication openly available.
- The research funder covers the APC (Article Processing Charges) in open access journals, and a budget for this is included in the project proposal.
- The researcher or department covers the APC costs themselves.
- You can make use of the Taverne Amendment, which allows to share the publisher’s version (version of record) of your article via the RUG institutional repository Pure six months after publication. In this scenario, publish your article closed access. The Medical Library will make ik open access available in due time.
Note: Research funders such as NWO, ZonMW, and European research funding projects do not permit this.

The University of Groningen Library (UB) and the Open Science Community Groningen (OSCG) invite you to submit your case study for the 6th annual Open Research Award (ORA) to celebrate openness in research and teaching.
The ORA award celebrates the many ways in which academics make their research or teaching more accessible, transparent or reproducible. Researchers and students are invited to submit case studies describing their experiences with open research and education practices, individually or in teams. The case studies ideally explore the benefits, challenges and difficulties of making open choices as well as positive experiences and successful outcomes. We are looking for candid accounts of academics’ motivations for making open choices, the impact the open choices had and the lessons that have been learned.
Staff members and students can submit case studies. All submissions will be screened for eligibility by a jury. The three winners will each be awarded €500.
Deadline: 14 November 2025, midnight
