This page is about pledges made prior to 2012. In 2012, the rate of pledging increased rapidly, especially in fields less beholden to conventional journals. As a consequence, the numbers pledging on their own blogs may now be too large to keep up with. A benefit of also pledging with a website like this one is that observers can see that large numbers have pledged.

Outside of this website, Open Access pledges have been made by institutions (such as universities and funders) and by individuals. There are two kinds of individual Open Access pledges. In author pledges, researchers pledge to make their own work OA, and in reviewing pledges other researchers pledge only to serve as referees for OA journals. (In the pledge we have formulated on this site, both Green and Gold OA are accommodated as the pledge includes reviewing manuscripts destined to be open because they’ll be put in free repositories – Green OA)
