Plan S is an initiative for Open Access publishing that was launched in September 2018. The plan is supported by cOAlition S, an international consortium of research funders. Plan S requires that, from 2021, scientific publications that result from research funded by public grants must be published in compliant Open Access journals or platforms.
- authors should retain copyright on their publications, which must be published under an open license such as Creative Commons;
- the members of the coalition should establish robust criteria and requirements for compliant open access journals and platforms;
- they should also provide incentives for the creation of compliant open access journals and platforms if they do not yet exist;
- publication fees should be covered by the funders or universities, not individual researchers;
- such publication fees should be standardized and capped;
- universities, research organizations, and libraries should align their policies and strategies;
- for books and monographs, the timeline may be extended beyond 2021;
- open archives and repositories are acknowledged for their importance;
- hybrid open-access journals are not compliant with the key principle;
- members of the coalition should monitor and sanction non-compliance.
