cOAlition S was announced on 4 September 2018 by 11 European national funders and the European Commission. It has grown to include funders from outside Europe (notably the Howard Hughes Medical Institute) and major charitable funders (Wellcome Trust, Bill & Melinda Gates Foundation as observer). Members commit to aligning their open-access policies with the Plan S principles. The coalition is governed by a Coordinator (Johan Rooryck since 2021) and produces guidance on price transparency, rights retention, transformative arrangements and the Journal Checker Tool that authors use to test compliance.
