The Postconciliar Roman Rite
Edition-specific studies of the postconciliar Roman Rite, distinct from the 1962 books. Each entry identifies its books, language, territory, cycle, and date where applicable. These books are widely called the Novus Ordo; this library names them by their own titles and dates.
