In 2022, 98,5 % of UMCG peer-reviewed articles were open access - including gold (37%), hybrid (31%) and green (27%) open access. The share of open access publications remained stable from 2021, but rose significantly compared to previous years (80% in 2020, 72% in 2019, 56% in 2018).
The steep rise registered in the last two years is largely due to the implementation of the new open access procedure which resulted in a significant growth of the green open access share. Nevertheless, researchers are encouraged to explore gold and hybrid open access possibilities with priority.
