This project aims to produce an online image-based edition of Cambridge, Pembroke College MS 25, a homiliary copied at Bury St. Edmunds in England near the end of the eleventh century, containing ninety-six Latin sermons that were originally composed on the Continent in the ninth century. This manuscript is important as the earliest and best surviving witness to a sermon collection known as the Homiliary of Saint-Pére de Chartres and also as the fullest example of a Latin homiliary that was used by Anglo-Saxon clergy as the basis for writing sermons in Old English to be preached to the laity.

Through its transmission history and its contents, Pembroke 25 bridges the worlds of Carolingian and Anglo-Saxon learning and dramatizes the close interrelations between Latin and Old English literature. The manuscript has long been recognized as a crucial document of Carolingian intellectual history and of late Anglo-Saxon preaching, but sixty of its ninety-six texts remain unpublished, it has never been subjected to a rigorous paleographical analysis, and because it exists in a single copy housed at Cambridge University Library, it is difficult to access (and access is discouraged because of the manuscript's fragile condition).

This new edition of Pembroke 25 will bring to light full editions of the ninety-six sermons accompanied by select modern English translations, notes, indexes, a glossary, digitized color images of all 181 folios of the manuscript, and essays on the background of the collection and its ties with Old English literature.
