abbey corn mill was located to the south-west of the abbey, near the River Ribble. The leat runs north-south along the base of the hill, cutting a bend in the river. The water supply was augmented via an additional channel from St Mary's Well situated to the north-east of the abbey. Books Only three books thought to have been in the abbey's library are known to still exist, with two of those now at Cambridge University. Both manuscripts were acquired by Archbishop Matthew Parker and either gifted to the University Library in 1574, or bequeathed to Corpus Christi College after his death in 1575. The first is now in two parts, Cambridge University Library, Ff. i.27 and Cambridge, Corpus Christi College, MS 66. It contains the earliest known English example of a group of similar world maps that includes the Hereford Mappa Mundi. Traditionally known as the Henry of Mainz Map, it is thought to have been created in the late 12th or early 13th century, perhaps at Durham Priory. The second manuscript is Cambridge, Corpus Christi College, MS 139, thought to have been written around 1164. The abbey's cartulary is part of the Harleian Collection at the British Library (Harley MS 112). Burials William de Percy, 6th Baron Percy and wife Ellen de Balliol (daughter of Ingram de Balliol).
