Here is the series of catecheses on the Psalms and Canticles of Lauds (Morning Prayer in the Liturgy of the Hours) by Pope John Paul II. This series follows John Paul II’s Catechesis on Salvation History and precedes John Paull II’s and Benedict XVI’s Catechesis on Vespers. It began on March 28, 2001, and concluded on October 1, 2003, and it includes 87 general audiences.
These audiences are available in book form from Liturgy Training Publications. As with the Catechesis on Vespers, these audiences are also published by the Catholic Truth Society, which is the official publisher of the Holy See in the UK.
All of these audiences are available on the Vatican Website under John Paul II’s Audiences for 2001, 2002, and 2003.
