The Power and Purpose of the Email Eprint Request Button

The email eprint request Button does not provide OA; it only provides "Almost OA." But that's infinitely better than no OA. And the Button (and the Immediate-Deposit/Optional-Access -- ID/OA -- Mandate, for which the Button was designed) make it possible for institutions and funders to adopt Green OA mandates that neither need to allow exemptions from immediate deposit nor do they need to allow publishers to dictate whether or when the deposit is made.
