A comprehensive essay about Jubilee by Mary Ann Rivera is on the web:
Jubilee: a magazine of the church and her people: toward a Vatican II ecclesiology
Logos: A Journal of Catholic Thought and Culture, Fall, 2007 by Mary Anne Rivera
"Jubilee magazine was a public proclamation of "Jubilate Deo, omnis terra "(Shout with joy to God, all the earth). For its founder, Edward Rice, the magazine proclaimed the "cheerfulness and joy" of everyday life and was a concrete expression of the believers' experience of God."
