A number of late additions (to the kalendar and in other marginal notes) suggest an association with Perugia (see van Dijk, 1956), but the location where the manuscript was first produced is uncertain. The manuscript has been at the Newberry Library since the late nineteenth 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.

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:
