PLAN S and other progress for Open Access to knowledge

Abstract:  The principle of Open Access (OA) is about the breaking of any paywall to the knowledge coming from research funded by public monies. After twenty years of statements not much has changed and the market of scientific journals is still in the hands of oligopolistic companies. Plan S is a disruptive initiative created by research funders in Europe and US which aims to foster the transition to Open Access by acting against hybrid journals and citation index. The Italian Institute for Nuclear Physics (INFN) has signed Plan S and, in close relationship with the Universities, the Conference of Rectors (CRUI), and the National Research Council (CNR), is outreaching the academic communities to discuss strengths, weaknesses, opportunities and threats.  In this work both a description of Plan S and a brief status report of other initiatives are given.
