<p>In March 2022, Science Europe, cOAlition S, Open Scholarly Communication in the European Research Area for Social Sciences and Humanities (OPERAS), and the French National Research Agency announced the release of an Action Plan for Diamond Open Access (Ancion et al. 2022). This Action Plan includes recommendations for supporting and expanding the diamond model of open access (OA). Whereas gold OA refers to publications made openly available to read on journals’ websites (often, though not necessarily, supported by article processing charges or APCs) and green OA refers to publications made free to read through deposit in a repository, diamond OA refers to publications that are free for readers and for authors (see “What are the Different Types of Open Access” from Open Access Australasia).</p>
