The editors of Adoremus get a little snarky:
One hundred and three years after Pope Pius X called for liturgical reform, and “actual participation” of the people at Mass, in Tra le sollecitudini;
Forty-three years after the Fathers of the Second Vatican Council approved the Constitution on the Liturgy, Sacrosanctum Concilium, which permitted use of vernacular languages at Mass;
On a very slightly more productive note (if you're a liturgy nerd), Adoremus also has a transcript of the USCCB debate leading up to the vote that approved the new liturgy translations, as well as the text of the widely-praised address by Bishop Arthur Roche of Leeds, England, Chairman of ICEL, that preceded the debate.
