Thanks to many efforts, all of Electronic Journal of Probability (EJP) and Electronic Communications in Probability (ECP) is now freely accessible on Project Euclid. This transition is facilitated by the Digital Object Identifier system. In Europe, the analogue of Project Euclid is the European Digital Mathematical Library (EuDML) which includes the French Numdam.
Project Euclid was developed and deployed by the Cornell University Library, with start-up funding provided by The Andrew W. Mellon Foundation, and is now jointly managed by the Cornell Library and Duke University Press. It was originally created to provide a platform for small scholarly publishers of mathematics and statistics journals to move from print to electronic in a cost-effective way. Through a combination of support by subscribing libraries and participating publishers, Project Euclid has made 70% of its journal articles openly available. As of 2015, Project Euclid provides access to over 1.2 million pages of open-access content.
