Daniel G. Tracy, Elizabeth A. Budd, and Thomas H. Teper write: “With increasing requirements for open access (OA) by funders, academic libraries have begun piloting so-called ‘transformative agreements’ with publishers. This study documents the broad success of two transformative agreement pilots at a large research university and argues that the growth of such agreements could help transition a broad proportion of research to OA at the university and within the consortium. The success of these agreements was true across disciplines and stages of career seniority.”
