Prometheus has had a hybrid publishing model with some material freely available and some available only on payment. From the beginning of 2021, Prometheus became totally open access with all its past and present content freely available to anyone. Material that was originally published as open access or as free access (such as editorials and our debate papers) remains clearly marked on the Prometheus website.
