Almost 100% open access achieved at the UG/UMCG
In 2021, 97% of UG/UMCG peer-reviewed articles and conference proceedings were open access - including gold (28%), hybrid (35%) and green (33%) open access. The share of open access publications rose from 69% in 2020.
This steep rise (+ 28% on last year) is largely due to the implementation of the new 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 Medical Library are responsible for implementing the regulations.
