The local Poor Clare Monastery has asked me to make known that they have a fairly large quantity of accompaniment books available for the cost of the shipping (probably about $3.00 media mail).

The accompaniment book contains organ accompaniment for the Gregorian Mass Ordinaries that were adapted for use in either English or Latin in 1994 by Mother Mary Francis, p.c.c.

They were adapted from the Accompaniment to the Vatican Kyriale by Achille P. Bragers (1937).

I have a few photos of the book available here: https://photos.app.goo.gl/62hlo6Un44X4sPnl2

If you would like to have a copy of this book, please message me directly.
