These Mass Texts are part of the Roman Missal, third typical edition (2011). This new missal has a mandatory first use date of the First Sunday of Advent, 27 November 2011 which includes the anticipated Mass of Sunday the evening before. None of these texts may be used at Mass before that date. Publishers are now in the process of preparing these missals. The national plans calls for shipping of the books on 01 October 2011.
The United States Conference of Catholic Bishops [USCCB] is, however, making a limited number of texts available for study and preparation purposes.
