More than 100 German universities and research institutions have entered into a national agreement with MDPI. The publication agreement negotiated by ZB MED comes into effect on 1 January 2025 and is valid until the end of 2026. Joining the consortium is still possible until the beginning of 2025. We are delighted by the high level of interest this agreement has already garnered, reflecting the strong demand for accessible and cost-effective open access publishing solutions among German research institutions. The aim of this new cooperation is to make gold open access publishing easier for the researchers and to reduce the administrative burden for librarians in Germany. The agreement includes substantial discounts on article processing charges (APCs) for corresponding authors from participating institutions. It offers flexible payment options, including centralized invoicing or individual payment of fees by researchers or their institutions. Additionally, the agreement features a flat-fee model that enables institutions to precisely plan expenses and optimize their library budgets.Press Release: https://www.mdpi.com/about/announcements/9999
