Resources for medieval musicology and liturgy
There are only ca. 100 folios (207 photos): http://cantus.edu.pl/gallery/13129
But the comlpete index is there and also on cantusdatabase. If you have a specific wish I can send you selected photos.

Thank you Bartosz Izbicki for your reply. I thought of you right away when I saw this question. All the best!
