The latest material in the manuscript appears to be Julian of Speyer’s Office of Francis, which has been dated recently to approximately 1235 (Miskuly, 1989).
An addition (possibly from the fourteenth century) has been made to the kalendar of the feast of the Roman church, St. Pancras de secretario (van Dijk, 1956). Other additions to the kalendar have been associated by van Dijk with a mid-thirteenth century Roman liturgical reform, (also van Dijk, 1956), suggesting that the manuscript was in Rome perhaps as early as the thirteenth century.
The differentiae of each mode have been numbered with a two-digit system: an upper-case letter indicating the final pitch of the differentia and a sequentially ordered numeral. Differentiae that vary in terms only of immediately repeated notes, presence/absence of liquesence or neumation are give the same differentia code, but are distinguished with a lowercase letter in the first column of the “Extra” field (see File Description).
Chants not found in CAO have been assigned arbitrary numbers beginning with "fra". The codes for differentiae and chants not found in CAO in this index are consistent with those used for the other Franciscan manuscripts in the database:
