The Roy Rosenzweig Prize for Innovation in Digital History is sponsored jointly by the AHA and the Center for History and New Media (CHNM) at George Mason University. This prize will be awarded annually to honor and support work on an innovative and freely available new media project, and in particular for work that reflects thoughtful, critical, and rigorous engagement with technology and the practice of history. The prize will be conferred on a project that is either in a late stage of development or which has been launched in the past year but is still in need of further improvements. Deadline: May 14, 2010. For more information and instructions on how to apply, see the Rosenzweig Prize page. There are a number of other AHA prizes with May deadlines, find them all here.
