Is there a Latin American model of diamond publishing? Exploring the journal university portals

Numerous initiatives and academic organizations have highlighted awareness of the marketization of scholarly publishing and the need to strengthen its future through the transition to diamond open access. Latin America is often presented as a model in this regard. However, the diversity of the region’s publishing landscape and the coexistence of different types of publishing infrastructures remain insufficiently examined. It is well‑known that this resilient ecosystem relies on open source non‑commercial platforms and indexing systems such as Redalyc, Latindex, Biblat and SciELO, as well as Open Journal Systems. Less emphasized is the central role played by universities, which possess the experience and capacity to sustain community‑led publishing initiatives. This article first presents a global cartography of indexed diamond journals updated to June 2025, based on an aggregated dataset of sources comprising 17,855 journals, highlighting Latin America’s contribution to quality diamond publishing. It then examines the results of a regional survey of university portals conducted between August and October 2025, covering 741 portals responsible for 10,823 active journals. Finally, it argues that supporting these institutional organizations offers a realistic pathway to advance diamond scholarly publishing, while acknowledging that each region should find suitable routes for its own academic journals.
