The document is the Brussels Declaration on STM Publishing signed by international STM publishers. It outlines several key principles: 1. Publishers' mission is to disseminate knowledge through economically sustainable business models and support academic freedom for authors. 2. Publishers organize peer review for STM journals, which is an irreplaceable process for scholarship. 3. Publishers launch and develop journals to benefit the scholarly community. 4. Current publisher licensing models have significantly increased access to research outputs, though publishers have heavily invested in digitization and growing literature volumes.
