The Helmholtzstraße library is open continuously from Monday to Friday from 8 a.m. to 4 p.m. It will also be closed from 24 December 2025 to 6 January 2026.
The visitor figures for the changed opening hours will be statistically analysed and will be supplemented by online surveys of our reading room visitors at the beginning of 2026. The aim is to gradually adapt the opening hours to the current demand situation.
