From the University of California’s Office of Scholarly Communication announcement:

The University of California (UC) will be hosting an Open Access Tipping Point Public Forum in Washington, DC on August 29th from 2:00-4:30 pm EDT. This free, interactive public event is intended to advance understanding of the value and opportunities associated with negotiating, participating in, and supporting transformative open access agreements for all stakeholders in the scholarly publishing community – publishers, societies, funders, libraries, and academic authors. We hope you’ll join us!
