We support a large praying community. We don't strive to be publishers of text, but rather facilitators of Liturgical prayer. For this reason our text and audio are kept closely in synch to facilitate this public celebration. When we provide a sung or chanted version of the Invitatory or Psalmody we use the Mundelein Psalter, which was created in order to facilitate the sung public celebration of the Liturgy of the Hours. The Mundelein Psalter is the first complete psalter containing the approved English texts of the Divine Office pointed for singing chant and available for public use. It is approved for use in the dioceses of the United States of America by the United States Conference of Catholic Bishops.
