In pursuit of open science, open access is not enough

After decades of debate on the feasibility of open access (OA) to scientific publications, we may be nearing a tipping point. A number of recent developments, such as Plan S, suggest that OA upon publication could become the default in the sciences within the next several years. Despite uncertainty about the long-term sustainability of OA models, many publishers who had been reluctant to abandon the subscription business model are showing openness to OA (1). Although more OA can mean more immediate, global access to scholarship, there remains a need for practical, sustainable models, for careful analysis of the consequences of business model choices, and for "caution in responding to passionate calls for a'default to open'" (2). Of particular concern for the academic community, as subscription revenues decline in the transition to OA and some publishers prioritize other sources of revenue, is the growing ownership of data analytics, hosting, and portal services by large scholarly publishers.
