Sustainable Open Access in Latin America: an analysis of business models, challenges, and strategic pathways 2015-2025

Studies report that diamond models—eschewing Article Processing Charges in favor of public or internal funding—tend to secure reliable funding and achieve inclusion in international indexes such as Web of Science, Scopus, SciELO, RedALyC, and Latindex.

Diamond models utilizing institutional funding, combined with open-source infrastructure and quality control measures, enable Latin American open access journals to maintain financial stability and achieve international recognition.
