Roman Sources for the History of American Catholicism, 1763–1939 is a comprehensive reference volume, researched and compiled by Matteo Binasco, that introduces readers to the rich content of Roman archives and their vast potential for U.S. Catholic history in particular. In 2014, the University of Notre Dame’s Cushwa Center for the Study of American Catholicism hosted a seminar in Rome that examined transatlantic approaches to U.S. Catholic history and encouraged the use of the Vatican Secret Archives and other Roman repositories by today’s historians. Participants recognized the need for an English-language guide to archival sources throughout Rome that would enrich individual research projects and the field at large. This volume responds to that need. Binasco offers a groundbreaking description of materials relevant to U.S. Catholic history in fifty-nine archives and libraries of Rome. Detailed profiles describe each repository and its holdings relevant to American Catholic studies. A historical introduction by Luca Codignola and Matteo Sanfilippo reviews the intricate web of relations linking the Holy See and the American Catholic Church since the Treaty of Paris of 1763. Roman sources have become crucial in understanding the formation and development of the Catholic Church in America, and their importance will continue to grow. This timely source will meet the needs of a ready and receptive audience, which will include scholars of U.S. religious history and American Catholicism as well as Americanist scholars conducting research in Roman archives.

O'Donoghue's book, which is written as a traditional historical narrative, while also utilizing a comparative approach, is concerned with the life of Catholic religious teaching brothers across the English-speaking world, especially for the period 1891 to 1965, which was the heyday of the religious orders.
