Lambeth Palace Library, which dates from a bequest by Archbishop Bancroft in 1610, is one of England's major repositories of medieval manuscripts. More than half of the ninety-six manuscripts and documents containing items of Middle English prose were already present when the library was temporarily transferred to Cambridge in 1647. In the succeeding centuries further manuscript materials have continually been added, and within the last few years the library has become home to the older part of Sion College Library, an event that has added a further seven manuscripts to the present handlist. The collection at Lambeth is large enough to be fully representative of the corpus of Middle English prose: the Brut, the Wycliffite Bible, and Love's Mirror, for example, are all present, in some cases in multiple copies, as are writings by Hilton and Rolle. There are sermon cycles (including an almost complete set of Wycliffite sermons), medical recipes, historical works, and anthologies of religious treatises. Altogether the current handlist indexes almost 800 separate items, ranging from the veterinary to the liturgical. O.S.
