In what communio is this passage from Wisdom 16 used?

℣. Panem de caelo praestitisti eis.

℟. Omne delectamentum in se habentem.

℣. You gave them bread from heaven.

℟. Containing within itself all sweetness.

Is there an on-line index listing the psalms and canticles sung in the Graduale Romanum?

I need to find when Wisdom 16:20-21 is sung in the Graduale Romanum.

Grateful in advance,
Paul
