Open Access Regulation (OAR)

In accordance with the Open Access Regulation (OAR), the published versions of all short scientific works by employees of Erasmus University Rotterdam, that have not been published Open Access in a journal, will automatically be made publicly available 6 months after the first publication in the institutional repository.

How does it work?

The OAR is based on Article 25fa of the Dutch Copyright Act, also known as the Taverne amendment, which gives researchers the right to make short scientific work freely available to the public after a reasonable period of time. A publisher cannot contractually limit that right.

For their work to be made public under the OAR, researchers do not need to take any action on their end. The University Library will take care of opening up all qualifying publications. The Open Access Regulation only applies to short scientific work.


In case you do not want a publication to be publicly shared on the basis of the Open Access Regulation, you may request an opt-out. You will be asked to give reasons for your decision.
