In 1991 and again in 1992, Dr. Keefe applied to Duke University for funds to supplement her Grant-in-Aid from the American Council of Learned Societies. The funds supplemented the earliest stages into a research project she called "The Education of a Christendom: Clerical Instruction and Popular Belief in Ninth-Century Europe," which would ultimately be published as The Making of Christendom (2012).
Hard copies of Dr. Keefe's grant applications can be found in the Keefe Collection, Box 2, Folder 41.
