This is niche content but I'm imagining that there might be plenty of interest right now in articles that have been published behind a paywall, but have been accepted and published whilst containing the Plan S / cOAlition S Rights Retention Strategy language.
By 2022 this might be 'boring' but in 2021 I think it would be useful to provide a list of 10-30 articles across all the major publishers to help give people confidence in RRS - they can point to successful examples.
