Ouvrir la Science - « Journal Checker Tool » ou comment s’assurer qu’une revue est conforme au Plan S ( or how to ensure that a journal complies with Plan S)

From Google's English: 

"The coalition S announces the launch of the "Journal Checker Tool  " (JCT) in beta. The JCT is an online tool that gives clear and quick information to researchers on whether the journal in which they want to publish complies with the open access policy of the organization that funds their research, when this is aligned on plan S.

All they have to do is enter the name of the journal, select the funding body and the institution to which they are affiliated."
