Papal address to the Roman Rota are delivered in Italian. English versions of these addresses are available in W. Woestman, ed., Papal Allocutions to the Roman Rota 1939-1994 (St. Paul University, 1994); later editions through 2011 are also available. Review: J. Diermeier, The Jurist 72 (2012). A French collection of these addresses is available in J. Thorn, Le Pape s’adresse à la Rote, 1939-1994 (Université Saint-Paul, 1994).
