CORE welcomes the objectives of Plan S to advance openness in all research subject fields as described in its ten principles. Plan S, which was initiated by a coalition of 11 European research funders aims to further the adoption of open access to European funded research.
September 2018 saw the launch of Plan S, an initiative supported by the European Commission and various national public funding bodies (“cOAlitionS”) who, from 2020, will require that all articles by their grantees must be published immediately OA. The policy aims to accelerate the transition to OA with 10 principles and builds on an implementation guideline that aims to articulate a comprehensive operational roadmap for all stakeholders: funders, repositories, publishers and learned societies. A revised guideline, following a public consultation, is due in May 2019.
