United Dioceses of Dublin & Glendalough: The Red Book of Ossory Digitized and Online. “As efforts in the RCB Library to digitize and make available its resources to a worldwide audience continue, one of its most significant medieval manuscripts, TheRed Book of Ossory (RCB Library D11/2/1), is now available for public consultation on the Church of Ireland website…. The Red Book of Ossory contains 79 vellum leaves, and was composed largely in the 14th century during [Richard] Ledred’s time. Later entries were added, the latest from the reign of Elizabeth I. The Red Book derives its name from the colour of the leather binding, faded on the outside, but still visible inside the cover. Like other medieval episcopal registers, it contains a wide range of documents that defy classification, the choice of which depended on what was important to individual bishops, in this case by Ledred, whom Dr Empey makes clear in his presentation was ‘one of the most extraordinary bishops ever to occupy the see of Ossory’.” RCB Library stands for Representative Church Body Library.
