This book is in an extremely fragile condition and it has not been possible for it to be imaged, save for the front and back cover exteriors, and the first gathering rectos only foliated as ff. a-l. The paper is in a very poor state and cannot be stabilised, so it has not even been possible to foliate the manuscript throughout. CCCC MS 527, made in the fourteenth century in Bohemia or Germany, contains three texts: an alphabetical moral dictionary, a treatise on penance attributed either to Thomas of Chobham (d. after 1233) or more likely to Bartholomaeus de S. Concordio Pisanus OP (d. 1347), and finally 'De essentia dei' by pseudo-Jerome. The work on penance has a colophon dating its writing to 1395. This volume is part of the Elbing collection; a group of manuscripts which belonged to a Brigittine convent at Elbing (Elblag), near Gdansk. The collection was donated to Corpus Christi College by either Richard Pernham (1583?-1628) or his wife Mary, whose name is in many of these books.
