The Open Access Button has released "Arcadia Fund Supports Open Access Button to Improve Access to Research Without Subscriptions."
Here's an excerpt:
We're happy to announce that Arcadia, a charitable fund of Lisbet Rausing and Peter Baldwin, has provided the Open Access Button with a two-year, $420,000 grant to accelerate our work to release content behind paywalls and improve researchers’ ability to do their work without expensive subscriptions. . . .
We hope to expand usage of the request system outside the Open Access Button, where it is currently in development, to include inside ILL, repositories and other services where users hit paywalls.
