The vast majority of the western medieval manuscripts in St John's College Library are catalogued in Ralph Hanna's Descriptive Catalogue of the Western Medieval Manuscripts of St John's College Oxford (Oxford: Oxford University Press, 2002).
As part of the ongoing digitization project, these catalogue entries are gradually being published online on Medieval Manuscripts in Oxford Libraries . Some of our western medieval manuscripts are also currently available on Digital Bodleian
