Currently there are 8 of the 27 Signatures in the collection digitized. Of these ten manuscripts were part of the collection of Stefano Borgia, Borg.gr.6,7,9,10,11,12,18,19,21,22 and the rest were later acquisitions. The final codex entered the collection as a donation to Pope Pius VII from Maximos III Mazlum, Melkite Archbishop of Abydos, Mira and eventual Patriarch of Antioch.

The image to the left containst the 4th-6th membranes of Borg.gr.27, a liturgical roll made in Salerno between 1085 and 1111. The various membranes have been dyed shades of red and black, and written on with silver and gold ink. Although in Greek, it was comissioned long after Byzantine control of Sicily ended, and is datable by reference to Duke Roger of Sicily.
