Parish Book of Chant (2nd Ed.) Source

I'm wondering if anyone who was involved in compiling The Parish Book of Chant can point me to the source of the Responsorial Psalm "Miserere mei, Deus" (number 8 on pg. 8), for both text and music, and rubric, since I can't seem to find it in this form in the Lectionary or the Graduale Simplex.

Thanks.
