WINDSOR, Berkshire, Royal collegiate chapel of St George
Discussion of the library by J. M. W. Willoughby, The Libraries of Collegiate Churches, CBMLC 15 (2013), 861–80, reprinted as The Medieval Library of St George's Chapel, Windsor Castle: Documentary Sources (Windsor 2014). He considers the question of the date of arrival of the manuscripts at Windsor. Since most of them are older than the college and ex-monastic, it is a possibility, as Ker noted, that they were not at Windsor before the Dissolution. In fact, Willoughby finds that the majority, and certainly those with pressmarks, came probably in the late 15th century.
