This catalogue describes 24 manuscripts from the collection of Thomas Ryburn Buchanan presented to the Bodleian Library in 1939 and 1941, including illuminated manuscripts from before the mid-sixteenth century. The collection consists primarily of late medieval devotional books from France, the Netherlands and renaissance Italy. It includes "Books of Hours", half of which are French and date from the fifteenth or early sixteenth century, a Bridgettine Breviary, a Milanese Breviary, a ferial Psalter, a Psalter of c 1300 and three Italian humanistic texts. A notable feature of the collection is the number of manuscripts with early and fine bindings. The illustrated catalogue gives detailed descriptions of the manuscripts - their texts, illumination, and codicological characteristics (including bindings).
