Thanks to a very special donor with a far-seeing vision, three fantastic books from the past have been digitized and thereby liberated into the infinite sector of the global commons. Many, many priests who celebrate the extraordinary form will rejoice at this news. These books that cover chants for Holy Week have been nothing short of impossible to obtain. You see them sometimes in choir lofts that miraculously escaped the great gutting of the late 1960s. Now they are back. If you print them, they appear on 8.5x11 sheets. I decided to forgo the color for load speed and convenience.
