AAU, ARL, and APLU have established the SHARE Steering Group.
Here's an excerpt from the announcement:
The Association of Research Libraries (ARL), the Association of American Universities (AAU), and the Association of Public and Land-grant Universities (APLU) today announced the formation of a joint steering group to advance a proposed network of digital repositories at universities, libraries, and other research institutions across the US that will provide long-term public access to federally funded research articles and data.
The steering group will oversee a feasibility study, guide policy, and explore governance structures necessary for prototyping and implementing the network. This repository network, the Shared Access Research Ecosystem (SHARE), is being developed as one response to a White House directive instructing federal funding agencies to make the results of research they fund available to the public.
