‘Taverne Amendment’: Article 25fa of the Dutch Copyright Act allows academics employed by a Dutch University to share short scientific works

This is one of the “Five tips to make 100% open access a reality” published daily during Open Access Week 2020.

Anamendment to the Dutch Copyright Act (in Dutch: Auteurswet) has made it much easier to share publications quickly in the Leiden Repository. Article 25fa of the Dutch Copyright Act (‘TaverneAmendment’) allows academics employed by a Dutch University to share short scientific works (for example, articles and bookchapters), regardless of any restrictive publishers' guidelines. On the basis of the Taverne Amendment, these academics can share the published version after six months, even if the embargo period is longer, or you are a co-author, or your publication was published by an international publisher.

Article 25fa Dutch Copyright Act (DCA)

The maker of a short scientific work, the research for which has been paid for in whole or in part by Dutch public funds, shall be entitled to make that work available to the public for no consideration following a reasonable period of time after the work was first published, provided that clear reference is made to the source of the first publication of the work.


A period of publication after six months applies under the following conditions:

  • The publication is funded wholly or partly with Dutch public funds.
  • The maker(s) has/have an employment contract with an institution affiliated to the VSNU; the makers can be both authors and co-authors.
  • It is a short scientific work; this has the length of a scientific article or book chapter in an edited collection.

A proposal for broad implementation of 25fa DCA at Leiden University is now with the board of management. Academics employed at Leiden University will be informed as soon as the proposal has been adopted. After the adoption of the policy, academics can upload their published article via LUCRIS and choose the License ’25 fa Aw (Taverne)’. If necessary, you can upload the article under a nembargo of six months after the work was first published.
