On September 28, 2012, Joseph A. Komonchak published his translation of some of Vatican II's Preparatory Commission's docuмents, namely:

*On the sources of revelation
*On defending intact the deposit of faith
*On the Christian moral order
*On chastity, marriage, the family, and virginity

I especially like Ch. 5 THE DEVELOPMENT OF DOCTRINE and Ch. 1 THE KNOWLEDGE OF TRUTH of On defending intact the deposit of faith. It actually cites, e.g., Humani Generis and Lamentabili!

On the sources of revelation is the one the council fathers rejected by a simple majority (1,368) on Nov. 20, 1962; which Ratzinger harshly criticized (Ratzinger Reader pp. 258 ff.); and which John XXIII thereafter called upon a mixed commission (incl. Card. Frings et al.) to redraft. It it is also what morphed into Dei Verbum.

Ratzinger in Ratzinger Reader regarding the first schema ("Schema Constitutionis Dogmaticae de Fontibus Revelationis"):

It was precisely this attitude which the fathers had to assert against the proposed text ["Schema Constitutionis Dogmaticae de Fontibus Revelationis"]. The texts almost exclusively relied upon the Latin theology of the last hundred years in continuation of the fight against Modernism, and in so doing, these texts were obviously threatened by a narrowness in which the wide scope of Catholicism could scarcely be detected.

So scholasticism (= Thomism; cf. Pascendi §45: "let it be clearly understood above all things that the scholastic philosophy We prescribe is that which the Angelic Doctor has bequeathed to us") isn't Catholic‽
