One of the collections that contains a copy of Wimbledon's Redde rationem vilicationis tuae in Latin, Cambridge, University Library MS Ii.3.8, is a composite paper codex, written in a variety of hands that date from the early to the late fifteenth century. Besides sermons of various lengths and degrees of completeness, it also contains free-standing exempla, commonplaces, and sermon outlines, as well as an entire ars praedicandi and three treatises on the Decalogue. Hence it presents itself as a preacher's notebook rather than a simple sermon collection. On its front flyleaves appears an index listing fifty-eight sermons with their themata and folio references. Many sermons are incomplete, and the copyists have left blank spaces together with such remarks as “vacat” and “non plus in copia,” indicating that their exemplars were defective. With one exception (St. Thomas the Apostle) the sermons are all de tempore, but do not follow the liturgical calendar. Sermons for Lent and Easter predominate.

After a series of rather unremarkable sermons, the manuscript preserves a number of pieces full of English material – not only short glosses, translations of quoted authorities, and divisions, but popular sayings and longer verse items, even genuinely macaronic structures. These vernacular items have repeatedly attracted the attention of literary scholars.
