UG/UMCG open access uptake stable at 97%

In 2023, 97% of UG/UMCG peer-reviewed articles and conference proceedings were open access - including gold (30%), hybrid (41%) and green (26%) open access. The share of open access publications remained stable from 2021, but rose significantly compared to previous years (69% in 2020, 64% in 2019, 55% in 2018, 51% in 2017 and 37% in 2016).

The steep rise registered in the last three years is largely due to the implementation of the open access procedural regulations which resulted in a significant growth of the green open access share.

Open access procedural regulations (Taverne amendment)

As of May 2021, publications by UG/UMCG authors are automatically made available through the institutional repository (Pure) six months after their first publication in a journal or edited book. This is possible thanks to Article 25fa of the Dutch Copyright Act (also known as Taverne amendment), which grants Dutch-affiliated researchers the right to make their short academic works open to the public for free after a short embargo period.

The University of Groningen Library (UB) and the Central Medical Library (CMB) are responsible for implementing the regulations.
