Launched in 2019, the DEAL-Wiley contract enables thousands of scientists in Germany to publish their articles open access in Wiley journals each year, thereby increasing the visibility and reach of their research. Over 500 universities and research institutions actively participate in the agreement, providing their users with access to the full Wiley journal portfolio. Thanks to their participation commitments, the shareholders of MPDL Services gGmbH, the operating entity of the DEAL agreements, have concluded that the nationwide agreement will be extended by an additional year, an option made available under the terms of the agreement. Wiley has announced the signing of the 2023 extension with MPDL Services gGmbH in a press release.
