OA Barometer 2025

Data on the transformation from subscription systems to open access

According to Forschungszentrum Jülich’s Open Access Strategy, the Central Library is responsible for overseeing the transition from subscription to open access systems and for managing expenditure on subscription journals so as to ensure that sufficient funds are available for gold open access article processing charges (APCs).

In 2025, the average publication fee paid rose from € 2,058 in 2024 to € 2,245 (9 %). Of particular significance here is the sharp increase of 40 % at Springer Nature, attributable on the one hand to higher publication fees for gold OA journals and on the other to a change in billing under the DEAL agreement. Jülich had previously enjoyed favourable terms under its existing contracts; the transition period has now come to an end.

In 2022, the Central Library (ZB) began adding details on the information budget to the Open Access Barometer. In addition to expenditure on journals and journal publications, as shown in the Open Access Barometer, the information budget includes other types of expenditure and ZB sources of financing.
