The Open Library of Humanities (OLH) is a non-profit Open Access publisher for the humanities and social sciences and at the same time a multidisciplinary mega-journal for the humanities. The journals and publications are not financed by so-called Article Processing Charges (APCs), but by consortial contributions from participating libraries and institutions. Neither for the reading access to the journals nor for the publishing costs arise for the scientists themselves. The SLUB also participates in the OLH. The term is initially until December 2023.
