This volume deals with books, published in the Low Countries, presently housed in the Maurits Sabbe Library, K.U.Leuven (Belgium). The seventy book reviews, written by some fifty specialised scholars, convey an idea of the richness of the Jesuitica collection at this library, which includes the large Jesuitica collections of the Flemish and Dutch Jesuits, introducing the research community to the plethora of possibilities for further inquiry. The selection comprises a great variety of topics: organization and history of the Society, theology in all its aspects, education, missions, history, geography and science. Even pamphlets and books in which the Jesuits are the object of slander are dealt with. Not only does this book provide a glimpse of the many local and foreign Jesuits and the contexts in which they operated during those centuries, but it equally sheds light on the Low Countries book production in the period of the 'Old Society', 1540-1773.
