The intersection of diversity, equity, and inclusion (DEI) with open access (OA) initiatives is gaining increasing attention within the scholarly publishing community. This article synthesizes key findings and initiatives from Latin America, Europe, and North America to address barriers and promote equitable access to scholarly research and knowledge. Because the preservation and dissemination of already-produced scholarly knowledge is largely dependent on libraries, archives, and museums, archival practices that include DEI and OA will be addressed.Latin America emerges as a pioneering region in the global OA movement, driven by public universities, scientific societies, and research foundations. However, challenges persist, particularly with the threat posed by Article Processing Charges (APCs) from commercial publishers. Despite these challenges, Latin America is experiencing rapid growth in OA publishing, with recent studies indicating a significant proportion of research being published through OA models. In Europe and North America, there is a growing recognition of the importance of promoting bibliodiversity and multilingualism in scholarly communications. Initiatives emphasize the need to support non-commercial publishing models and collaborative publishing models without article processing charges, while also encouraging collaboration, participation, and inclusion at all levels of the scientific process. The purpose of this poster is to communicate the overlapping issues related to DEIA and open access materials in a comparison between the three locations mentioned, and to share archival best practices to ensure marginalized communities enjoy access to open access scholarship.
