In 2025, Clarivate (the parent company of ProQuest) announced significant changes to its eBook purchasing model across the Ebook Central platform. These changes include the end of Demand-Driven Acquisition (DDA) and other single-title perpetual purchase options, with a shift toward subscription-based eBook access models for academic libraries.
