From the University of California Office of Scholarly Communication:
The Academic Senate of the University of California passed an Open Access Policy on July 24, 2013, ensuring that future research articles authored by faculty at all 10 campuses of UC will be made available to the public at no charge.
The policy covers more than 8,000 UC faculty and as many as 40,000 publications a year. By granting a license to the University of California prior to any contractual arrangement with publishers, faculty members can now make their research widely and publicly available, re-use it for various purposes, or modify it for future research publications.
Faculty on three campuses (UCLA, UCI and UCSF) will begin depositing articles in eScholarship on November 1, 2013. Progress on deposit implementation will be reviewed during the following year. Deposit of articles by faculty on the remaining campuses is expected to begin on November 1, 2014.
