This collection consists of a range of 19th and early 20th century manuscript correspondence, acquired by UCD Library from diverse sources since the foundation of the Catholic University. It includes letters from significant figures, some connected directly to the University, including: Cardinal John Henry Newman (1801-1890), Gerard Manley Hopkins (1844-1889) and Roger Casement (1864-1916).
The correspondence of Gerard Manley Hopkins was donated to UCD Library by Vernon Brooks in 1989 and makes up a large proportion of this collection. It consists of 43 letters and postcards written to Alexander William Mowbray, between 1863 and 1888. These have all been published in Further letters of Gerard Manley Hopkins, including his correspondence with Coventry Patmore, edited with notes and an introduction by Claude Colleer Abbott, 2nd ed., revised and enlarged (London: Oxford University Press, 1956).
