One of the routes to compliance with Plan S requirements requires depositing an Author Accepted Manuscript (AAM or postprint) in a Plan S compliant repository such as the TU/e institutional repository. However, not all publishers allow this type of self-archiving. cOAlition S has introduced a rights retention strategy that addresses these issues and allows authors to meet Plan S requirements.

What researchers are required to do
1. Follow grant conditions set by a funder
Grant conditions of cOAlition S funders will by default apply a prior open license (CC-BY 4.0) to all the future accepted author manuscripts of publications that will arise from their funding. You as the author will therefore be required to make all Author Accepted Manuscripts (AAM) Open Access without embargo as soon as your article has been published.
2. Notify publisher about your grant conditions
When submitting you manuscript for publication, you are requested to give a notice to the publisher that future AAM which will result from this submission was licensed with CC-BY 4.0 and will be made Open Access in an Open Access repository immediately after publication of the final version. cOAlition S provides the template language for such a notice:
“This research was funded in whole or in part by the [Funder name] [Grant number]. For the purpose of Open Access, the author has applied a CC-BY public copyright license to any Author Accepted Manuscript version arising from this submission”.
3. Deposit author accepted manuscript in an Open Access repository
Immediately after original publication date, deposit AAM in a Plan S compliant repository such as the TU/e institutional repository.
