Dictyus Cretensis is a small limp vellum binding that is part of the Derry and Raphoe Diocesan Library in Londonderry, Northern Ireland. No date was found on the book as the title page was missing a large portion. The vellum slips were broken with the case and textblock completely separated. In addition exposure to dry conditions caused the case to shrink and crack at the spine in several places. At some point the book was exposed to a spill of some kind as well as a large amount of dirt.
