tool, designed to assess the equity of scholarly communication models, has been officially launched today in its updated version following a comprehensive review of community feedback. Developed by a multi-stakeholder Working Group, comprising librarians, library consortia representatives, funders and publishers, and convened by cOAlition S, Jisc and PLOS, the tool aims to provide a framework for evaluating scholarly communication models and arrangements on the axis of equity. This collaborative approach ensured that the tool’s updated version addresses practical challenges faced by institutions, library consortia, funders, and publishers in evaluating equity within scholarly communication models and arrangements.
