The Notre Dame Center for Liturgy now has videos and transcripts of talks for background catechesis for implementation of the new translation of the Roman Missal by noted liturgists such as Fr. Jan Michael Joncas, Fr. Paul Turner and Sr. Joyce Ann Zimmerman. These talks would be good for Worship Committees, Catechists and parish groups. Find them at http://liturgy.nd.edu/webcatechesis/#turner.
