The latest indication of date in the manuscript is the name of Dominic (canonized in 1232) in the kalendar, in the main hand. Apart from that, no clear indications of date have been uncovered. 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 the Widescreen 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:
