Cambrai 38 is a rich source of chants and Offices not found in CAO ; several are printed in full within Analecta hymnica . They include Thomas Becket (Analecta hymnica vol. 13, pp. 242-5), Lambertus (Analecta hymnica vol. 26, 230-3), both Offices for Elizabeth of Hungary (Analecta hymnica vol. 25, pp. 253-8 and 260-4, respectively; the Finding of Firminus (Analecta hymnica vol. 13, pp. 145-7), and the Crown of Thorns (Analecta hynnica vol. 24, pp. 30-4). Because Cambrai 38 and Cambrai XVI both come from Cambrai cathedral, there is considerable overlap between these two sources. Offices that are contained fully or partially in both manuscripts include Corpus Christi, Vedastus, Mary Magdalene, Gaugericus, Augustine, the Elevation of Elizabeth of Hungary, and Catherine. Because of Cambrai's proximity to Arras (at one time they were under the same bishop), Cambrai 38 and Arras 893 also have features in common; however, Arras 893 follows the monastic cursus, so its Offices do not correspond exactly to those in Cambrai 38. The Offices of Corpus Christi, Nicasius, the Finding of Firminus, and Vedastus appear in both of these manuscripts.
Each chant not found in CAO is assigned an arbitrary number prefixed by "cam". Differentiae are identified with numbers chosen arbitrarily; the numbering of differentiae in this file corresponds to that in the file for Cambrai XVI.
