A collection of papal bulls and rescripts, some of which were addressed to the Archbishop of Canterbury, but the majority of which relate to monastic houses, which came to Lambeth following the dissolution of the monasteries. The collection was arranged by A.C. Ducarel in the 18th century and bound up as MSS. 643-4. In 1960, the collection was disbound and numbered.
A Micropublication of the papal bulls is available from World Microfilms in "Lambeth Palace Library: the medieval manuscripts" section II (Law MSS.), reel 18.
