Here are some excerpts from the Jerome Biblical Commentary, a book produced by the contributions of a large group of Catholic scholars as outlined in the editor's preface:
"The question of the Catholic interpretation of the Bible constantly reappears. It seemed to the editors that the best way to expose the misunderstanding implicit in this question was to produce a commentary written entirely by Catholics. This would allow readers off all persuasions to see a representative group of Catholic scholars at work – not the isolated and allegedly liberal mavericks, but some fifty contributors teaching in the Catholic colleges and seminaries in the United States, Canada, and abroad."

In the section entitled Canonicity, the issues surrounding the acceptance of the deuterocanonicals into the canon is discussed:
"Doubts about the deuterocanonical books keep recurring in the history of the Church among those who are aware of the Jewish canon. Those who prefer the shorter canon or express some doubt about the full canonical status of the deuterocanonicals include Cyril of Jerusalem, Gregory Nazianzen, Epiphanius, Rufinus, Gregory the Great, John Damascene, Hugh of St. Victor, Nicholas of Lyra, and Cardinal Cajetan.
As mentioned earlier, the Council of Trent accepted definitively the deuterocanonicals, and it did so directly in opposition to the Protestant preference for the Jewish canon. Although as Catholics we accept the statement of the Council as binding in faith, it is wise for us to know some of the difficulties that surround this statement. Even on the eve of the Council the Catholic view was not absolutely unified, as the mention of Cajetan in the preceding paragraph clearly indicates. Catholic editions of the Bible published in Germany and in France in 1527 and 1530 contained only the protocanonical books. The Fathers of the Council knew of the 4th century African councils that had accepted the deuterocanonical books, and they knew the position taken at Florence; but at the time of Trent, there were insufficient historical tools to reconstruct the real picture of the canon in the 1st century." (pg 523)
As with the New Catholic Encyclopedia, the authors of The Jerome Biblical Commentary outline some of the uncertainty that existed within the Catholic Church throughout history with regards to the OT canon.
