I was recently shown this PDF of a book, which gives the offices, pro aliquibus locis, for the Holy Land. Some of the offices correspond to the masses found at the back of the old missal, such as the Passion Masses on Fridays of Lent, or the additional feasts of the Blessed Virgin. Some are unique, such as the locally kept feasts of several Old Testament saints and other important saints to the church of Jerusalem. The PDF should be attached to this post.

My question is, does anyone have the corresponding chant for these offices? Or, does anyone know where to look? I speculate that they must exist somewhere, but I have had no luck finding them online so far.
