In a recent article for Nature Juan Pablo Alperin, co-scientific director of Simon Fraser University’s Public Knowledge Project (PKP), calls for more support to eliminate article-processing charges and opt for diamond open access in the Global North. Diamond OA is a level of open access that relies on faculty members editing journal articles rather than charging authors fees to publish or expecting payment from readers. Alperin writes that diamond OA has been embraced in Latin America while the global north has seen article-processing charges (APCs) become ubiquitous, particularly in more prestigious journals. Alperin calls for funds allocated to APCs to be invested into other supports for journals, and for journals to embrace the diamond OA model to reduce operating costs and raise journal quality.
