Two fragments of an important eleventh-century manuscript, missing for some years, were recently rediscovered by the staof Gonville and Caius College library. The manuscript is signicant both because of its attribution to the hand of ‘Eadwig Basan’, a major figure in the history of eleventh-century English script, and because it constitutes evidence for the use in late Anglo-Saxon England of a mass lectionary, a rare type of liturgical book. The fragments have now been assigned the class-mark 734/782a, in order both to associate them with and distinguish them from manuscript 734/782, a seventeenth-century paper catalogue of a bequest of books to the college, in whose binding they were originally preserved.
