Five major US universities (Cornell, Dartmouth, Harvard, the Massachusetts Institute of Technology, and the University of California, Berkeley) have announced that they have joined together in a compact for Open Access publication. Each university commits "to the timely establishment of durable mechanisms for underwriting reasonable publication fees for open-access journal articles written by its faculty for which other institutions would not be expected to provide funds". Other universities are being asked to sign on to the compact.
