Many of the worlds most critical challenges must be addressed globally. This presentation covers "Fostering Bibliodiversity in Scholarly Communications: A Call for Action" http://doi.org/10.5281/zenodo.3752923. Bibliodiversity = diversity, inclusion and equality in scholarly communications. Repositories support bibliodiversity and new roles and functions for repositories are discussed. Diversity is an important characteristic of any healthy ecosystem, including scholarly communications. Diversity in services and platforms, funding mechanisms, and evaluation measures will allow the scholarly communication system to accommodate the different workflows, languages, publication outputs, and research topics that support the needs and epistemic pluralism of different research communities. In addition, diversity reduces the risk of vendor lock-in, which inevitably leads to monopoly, monoculture, and high prices. As we transition to open access and open science, there is an opportunity to reverse this decline and foster greater diversity in scholarly communications; what the Jussieu Call refers to as bibliodiversity. Bibliodiversity, by its nature, cannot be pursued through a single, unified approach, however it does require strong coordination in order to avoid a fragmented and siloed ecosystem. Building on the principles outlined in the Jussieu Call, this presentation explores the current state of diversity in scholarly communications, and issues a call for action, specifying what each community can do individually and collectively to support greater bibliodiversity in a more intentional fashion. We are calling on the community to take concerted efforts to foster bibliodiversity through several specific actions.
