Often assumed to be a self-evident good, Open Access has been subject to growing criticism for perpetuating global inequities and epistemic injustices. it has been seen as imposing exploitative business and publishing models and as exacerbating exclusionary research evaluation culture and practices.Achieving Global Open Access: The Need for Scientific, Epistemic, and Participatory Openness (Taylor & Francis, 2024) engages with these issues, recognizing that the global Open Access debate is now not just about publishing and business models or academic reward structures, but also about what constitutes valid and valuable knowledge, how we know and who gets to say. the book argues that, for Open Access to deliver its potential, it first needs to be associated with "epistemic openness", a wider and more inclusive understanding of what constitutes valid and valuable knowledge. it also needs to be accompanied by "participatory openness", enabling contributions to knowledge from more diverse communities. interacting with relevant theory and current practices, the book discusses the challenges in implementing these different forms of openness, the relationship between them and their limits.Stephen Pinfield is Professor of Information Services Management at the University of Sheffield, UK, and a Senior Research Fellow at the Research on Research Institute (RoRI).Xiaoli Chen is project lead at DataCite, a non-profit organization that provides open scholarly infrastructure and supports the global research community to ensure the open availability and connectedness of research outputs.
