The road to sustainability: Examining key drivers in open access diamond journal publishing

Despite the rising interest in open access (OA) diamond journals as a scholarly journal publishing model, their sustainability remains a pressing concern. Using the Open Access Diamond Journals Study (OADJS) Dataset, we examined the characteristics and factors of OA diamond journal publishing that are associated with high sustainability. From 1335 journals, 476 journals with low sustainability and 438 journals with high sustainability were selected and compared. Our analysis revealed that factors such as the region and official language of the publishing country and the discipline, ownership, and financial status of the journal were significantly associated with sustainability. Journals owned by government or national agencies, those with financial stability, and those promoting open practices like unrestricted text and data mining are more likely to be sustainable. This study also discusses the implications of these findings for the future of scholarly publishing and the open science movement. Ultimately, we emphasize the need for national and international support to enhance the sustainability of OA diamond journals and propose that a collective approach involving policymakers, funding agencies, and journal administrators is crucial for fostering a sustainable open access ecosystem.
