One. While the official feedback phase on the revised S principles and transposition policies has expired, cOAlition S is still looking for community input. On 28 August 2019, cOAlition appointed Johan Rooryck, Professor of French Linguistics at Leiden University, as open access champion under the “Work Plan and Priority Actions for cOAlition S”. In the announcement, Plan S said: “In its role as an open access champion, Rooryck cOAlition S will be represented in meetings with external stakeholders such as funders, researchers, librarians and publishers. He will present Plan S, listen to the thinking and develop plans to help participants adapt to a changing editorial landscape. It will also advise COAlition S on how the transition to full and immediate open access can be implemented as effectively as possible. The “Work Plan and Priority Actions for cOAlition S” also includes cooperation with “publishers, companies, consortia and others, in order to develop clearer approaches to transformative arrangements towards full and immediate open access”. Plan S also announced a monitoring framework “that will allow funding agencies that are signatories to Plan S to track or monitor the main positive and negative effects of those effects.” Potential Areas of Action in Plan S that the framework will address include the employment/evaluation of researchers and the choice of journal. Today, under the dominant but outdated subscription model, libraries pay a flat fee for access to magazine packages, and authors who wish to publish Open Access under a subscription or a “hybrid” journal otherwise pay the Article Processing Charges (API). In transformation agreements, hybrid publishing fees are contained and revenue streams are carried forward: authors no longer pay APIs and their institutions (via their libraries) instead use previous subscriptions to pay publishers for their editorial services related to the publication of articles accepted in open access. While I disagree with Adam`s general point – for many reasons that others will certainly be happy to point out – it is an interesting point (also mentioned in the interview with Mandy Hill and Chris Bennett, but from the publisher`s point of view): what will make these agreements a success for libraries in the long run? Plan S describes transformative agreements as a transition option that allows subscription fees to be reallocated to cover costs published with open access. . .
