“De Gruyter is expanding its Subscribe-to-Open program DG2O, with plans to transform an additional 37 journals into open access by 2025.
Among the journals in the DG2O program that will switch to open access in the coming year are particularly renowned titles such as the Historische Zeitschrift, founded in 1859, the Archiv für Geschichte der Philosophie, first published in 1888, as well as esteemed periodicals committed to critical perspectives on socio-political questions such as Analyse und Kritik (founded in 1979) and feministische studien (founded in 1982). […]
“As editors of the Historische Zeitschrift, we are very pleased about this step towards accessibility,” say Prof. Julia Hillner and Prof. Andreas Fahrmeir, continuing: “We find it particularly important that the journal does not charge publication fees as before and thus remains accessible to authors regardless of their status in the academic system.””
