ABSTRACT
I first met Billy and Neans O'Sullivan and enjoyed their hospitality in 1956, when I had gone to Trinity to examine many of its manuscripts, primarily those including Middle English,1 but also ones containing Latin spiritual texts associable with the English Carthusians and Brigittines. As Billy is particularly interested in questions of provenance it seems appropriate here to list the books I know of which bear evidence of having belonged to or been made by English Carthusian monks but have not yet been linked firmly with a specific charterhouse, which would qualify them for entry in Medieval libraries of Great Britain or its Supplement?
