Let the Trumpet Sound; The Life of Martin Luther King Jr. received the Robert F. Kennedy Center for Justice and Human Rights 1983 Book Award presented annually to the book that "most faithfully and forcefully reflects Robert Kennedy's purposes – his concern for the poor and the powerless, his struggle for honest and even-handed justice, his conviction that a decent society must assure all young people a fair chance, and his faith that a free democracy can act to remedy disparities of power and opportunity." A decade later, Oates received the 1993 Nevins-Freeman Award of the Chicago Civil War Round Table for his historical work on the American Civil War.
