We have extensive holdings of church history throughout the majority of our collections. However we also have a collection specifically devoted to ecclesiastical history, concentrating on the history of the Papacy. Particular strengths of the collection relating to the medieval Church include an extensive run of J. P. Migne’s Patrologia Latina (several volumes of the Patrologia Graeca can be found in the library’s Byzantine collection), an extensive collection of published papal letters from the thirteenth and fourteenth centuries, published sources of medieval canon law, as well as numerous works on the religious orders.
More recent centuries of ecclesiastical history are not neglected either. As well as primary sources of the early modern and modern histories of the religious orders, including a sizeable sub-collection on the Jesuits, we have various published sources from the modern ecumenical councils, such as the Council of Trent and Vatican II, as well as individual works and published interviews from the papacies of John Paul II and Francis.
