Some of Callahan's other works include In the African-American Grain: The Pursuit of Voice in 20th Century Black Fiction, Ralph Ellison's Invisible Man: A Casebook, and The Illusions of a Nation: Myth and History in the Novels of F. Scott Fitzgerald. Callahan also edited Ellison's short story collection Flying Home and co-edited with Albert Murray the Modern Library edition of Trading Twelves: The Selected Letters of Ralph Ellison and Albert Murray. As Darryl Pinckney has observed: "Thanks to Callahan, there are more Ellison titles now than existed during his lifetime."[1]
