“Overview. The Community of Open Scholarship Grassroots Networks (COSGN), includes 107 grassroots networks representing virtually every region of the world and every research discipline These networks communicate and coordinate on topics of common interest. We propose, using an NSF 21-515 Implomentation grant, to formalize governance and coordination of the networks to maximize impact and establish standard practices for sustainability. In the project poriod, we will increase the capacity of COSGN to advance the research and community goals of the participating networks individually and collectively, and establish governance, succession planning, shared resources and communication pathways to ensure an active community sustained network of networks By the end of the project poriod, we will have established a self-sustaining notwork of networks that leverages disciplinary and regional diversity actively collaborates across networks for grassroots organizing, and shares resources for manum impact on culture change for open scholarship.”
