About 1350 the Benedictine monk Henry of Kirkestede, prior of the royal abbey of St. Edmund at Bury St Edmunds in Suffolk, and traditionally known as Boston Burienis, compiled a union catalogue of manuscripts in English libraries entitled Catalogus de libris autenticis et aposcrifis. He named 674 authors and assigned to them about 3900 works.
