Orbis Books, the imprint of the Maryknoll order, has been a small but influential publisher of liberation theology works, founded by Nicaraguan Maryknoll priest Miguel D'Escoto with Philip J. Scharper in 1970. It was the first to publish Gustavo Gutiérrez's seminal work A Theology of Liberation in the United States. It also published Ernesto Cardenal's The Gospel in Solentiname, and Richard Millett's Guardians of the Dynasty, a study of Nicaragua's National Guard. In 1976, they became the first publisher of future anti-apartheid activist Allan Boesak, and published Sebastian Kappen's Jesus and Freedom in 1977. In the 1980s, they carried titles by Daniel Berrigan and Phillip Berryman. Later authors include Haiti's Jean-Bertrand Aristide and the South African missiologist David Bosch. Currently, its editor-in-chief is Robert Ellsberg.
