JER7177: I am not sure I would strongly recommend any of the books cited by ImmaculataFides above. They represent a rather decided view with regard to the liturgical reforms (they are opposed), sometimes seeming to imply bad faith on the part of scholars, liturgists, bishops, priests, and learned lay people, as well as at least naivete on the part of two popes. I note that the “Ottaviani Intervention” is cited by the SSPX as one of their legions of reasons to condemn the Council and remain at odds with the Church. I don’t want to impugn the authors of the works mentioned, by the way, or ImmaculataFides. Una Voce, the organization over which Michael Davies presides, is recognized by the Church and, while holding particular views toward the liturgy, is certainly a good faith organization.
I don’t have off-hand any particular works to cite regarding the history of the liturgical reform (which is fascinating), but I would encourage you to look for them. One thing to mention is that it started long before most people think–long before the Council, in fact! Our current Missal, which is a wonderful effort on the part of scholars, liturgists, bishops, priests, and learned lay people, as well as two popes, represents the latest chapter in that long history of the Church trying to bring its most cherished treasure-the Eucharist–to the Faithful! And I would echo Pfaffenhoffen above: It was a terrible scandal when the ancient prayers were translated from the Greek! But thank goodness that the Church was willing to be faithful–ever faithful–to its mission of bringing the Eucharist to the Faithful! Where would any of us be if the Church had demurred?
