The Jesuitica is a Jesuit project at the Faculty of Theology and Religious Studies at the KU Leuven, Belgium that facilitates research on the history and spirituality of the Society Jesus.

The project houses an invaluable collection of some precious manuscripts, over three hundred incunabula, more than a hundred and seventy thousand rare books from the sixteenth to the eighteenth centuries, besides other rare books from later years. This collection spans the pre-suppression (1540-1773) as well as the post-suppression (after 1814) periods of the Society of Jesus and deals with as varied topics as the history of the Jesuit order, its mission territories, theology, arts and sciences, literary works besides more general writings.1 These volumes were acquired over several decades from Jesuit communities and colleges located within the Low Countries in Flanders and the Netherlands. The Jesuitica collection now constitutes an important part of the cultural patrimony of this region and is presently housed within the Maurits Sabbe Library of the KU Leuven.2

The Jesuitica project website provides a comprehensive way of accessing, collaborating and researching on the Jesuitica collections.
