Copyright Dr. Heather Morrison, All Rights Reserved (explanation below).mThis article presents important research and merits publication; conclusions are basically sound and recommendations appear timely and sensible. One major substantive point of potential confusion remains. This confusion is evident is PlanS implementation guidance per se which states: “cOAlition S acknowledges that some publishers have established mirror journals with one part being subscription based and the other part being Open Access. Such journals are not compliant with Plan S unless they are a part of a transformative agreement since they de facto lead to charging for both access and publishing in the same way as a hybrid journal does. Funding for publishing in such journals will only be supported under a transformative agreement”.
