Abstract: [Purpose/Significance] With the continuous development of the open access (OA) movement, bibliodiversity is being analyzed and discussed within the framework of global open science strategy. In an inclusive knowledge society, information and knowledge resources should be readily available, interpreted and utilized in appropriate languages and formats. Established in 2019, the Global Alliance of Open Access Scholarly Communication Platforms (GLOALL) mainly includes six national journal publishing platforms, whose establishment and promotion will become a form of bibliodiversity and open access movement. The policies, resources and services of GLOALL's platforms reflect the emphasis on diversity in regions, languages, and academic evaluations, and are conducive to the collision and compatibility of multiple cultures and ideas emphasized by bibliodiversity. [Method/Process] Based on the theory of bibliodiversity research and combined with current OA practice, this paper mainly explains, compares and analyzes the policies, resources and services of GLOALL platforms. The concept of bibliodiversity was first proposed by Chilean publishers, during the creation of the "Editores independientes de Chile" collective in the late 1990s. Besides, "the International Declaration of Independent Publishers 2014" defined it as "cultural diversity applied to the world of books", that is, the critical diversity of products (books, scripts, eBooks, apps and oral literature) made available to readers. Re-examining the OA movement shows that OA under different paths should develop together and complement each other when necessary, rather than just encouraging and promoting one mode. [Results/Conclusions] The GLOALL platforms have similarities in strategic goals and construction principles, like promoting local scientific research, global OA and bibliodiversity. However, since each platform is not systematically constructed in a standardized way and is aimed at different countries or regions, there are differences in specific aspects such as policy formulation, resource construction and service operation. For this reason, these platforms are designed according to the actual situation and publishing needs of their respective countries, and form synergy through alliances to balance the global OA publishing pressure from some international publishing groups. In essence, this publishing market emphasis on the inclusiveness of global OA. The construction experience of GLOALL has certain reference significance for China to promote OA and build high-end academic exchange platforms. On the one hand, the GLOALL members are all national OA publishing platforms, promoting the OA movement through international cooperation to find a balance between unity and diversity, and between international development and local development. They have a positive effect on forming an academic exchange ecology that can not only develop bibliodiversity, but also support international academic research. More importantly, building platforms is a means, while exerting international influence is the goal. At present, green OA has the alliances such as COAR. While as for golden OA, in addition to transforming academic journals into OA, uniting the world's national open publishing platforms is another way. Therefore, research on GLOALL in terms of policies, resources, service can help China better grasp the opportunities in the OA movement, fill the gaps in the current service mechanism, and explore more suitable OA modes.
