Among the finest manuscripts are a 'Roman de la Rose' with 125 miniatures, a 'Piers Plowman', the 'Ormsby Psalter' and the famous 'Douce Apocalypse'.

The Index of Middle English Prose is an international collaborative project which will ultimately locate, identify and record all extant Middle English prose texts composed between c.1200 and c.1500, in both manuscript andprinted form in medieval and post-medieval versions. The first step towards this goal has been this series of Handlists, each recording the holdings of a major library or group of libraries. Compiled by scholars, Handlists include detailed descriptions ofeach prose item with identifications, categorisations and full bibliographical data. Every Handlist will also contain a series of indexes including listings of opening and closing lines, authors, titles, subject matter and rubrics. For students of the middle ages Handlists provide essential bibliographical tools and shed light on a wide range of subjects.
