On Pilgrimage:

Dorothy Day (1897-1980), whose cause for canonization is in process, was the co-founder of the Catholic Worker movement. Her other Orbis titles include Dorothy Day: Selected Writings, Loaves and Fishes, From Union Square to Rome, Peter Maurin: Apostle to the World (with Peter Sicius), and On Pilgrimage: The Sixties.

Robert Ellsberg, the publisher of Orbis Books, was a member of the Catholic Worker community for the last five years of Day's life, including two years as managing editor of her newspaper. He has edited four previous volumes of Day's writings, including her selected writings, her diaries, selected letters, and On Pilgrimage: The Sixties.
