There is no such thing as the extraordinary form of the Mass. Now Pope Benedict XVI, in his motu proprio Summorum Pontificum, writes: In this regard, it must first be said that the Missal published by Paul VI and then republished in two subsequent editions by John Paul II, obviously is and continues to be the normal Form – the Forma ordinaria – of the Eucharistic Liturgy. The last version of the Missale Romanum prior to the Council, which was published with the authority of Pope John XXIII in 1962 and used during the Council, will now be able to be used as a Forma extraordinaria of the liturgical celebration.
