This document summarizes a presentation on Plan S's price transparency framework for publishers. It includes an agenda for the presentation which will provide an overview of the requirements and frameworks, include experiences from publishers implementing them (PLOS and Springer Nature), and allow for discussion and questions. It then outlines the key aspects of the price transparency framework, including a two-part implementation guide and data collection spreadsheet. Publishers are encouraged to provide data according to this framework by July 2022 to remain eligible for Coalition S funding.
