Catholic Bible

A Catholic Bible is a Christian Bible that includes the whole 73-book canon recognized by the Catholic Church, including the deuterocanonical books.
The term "deuterocanonical" is used by some scholars to denote the books (and parts of books) of the Old Testament which are in the Greek Septuagint collection but not in the Hebrew Masoretic Text collection. The Canon of Scripture of the Old Testament recognized by the Catholic Church is based on the Septuagint version of the Old Testament because, while both the Hebrew scriptures and the Septuagint were used in the time of Christ, the Septuagint was used by the apostles and Early Christianity in the universal proclamation of the Gospel. Indeed, most of the quotations from the Old Testament appearing in the New Testament books are from the Septuagint, not the Hebrew scriptures. The Catholic Church, at the Council of Rome (382), and formally at the Council of Florence(1431-1449) and later the Council of Trent (1545-1563) settled the Canon of Scripture of 46 books in the Old Testament and 27 books in the New Testament for a total of 73 books. 
Lectionaries for use in the liturgy differ somewhat in text from the Bible versions on which they are based. The Vulgate is the official Bible translation of the Latin Church, but translating from the original Hebrew, Aramaic, and Greek has been encouraged since Pius XII issued the encyclical letter "Divino afflante Spiritu" in 1943.
Books included.
The Catholic Bible is composed of the 46 books of the Old Testament and the 27 books of the New Testament.
Deuterocanon.
Tobit, Judith, 1 Maccabees and 2 Maccabees, Wisdom, Sirach, Baruch, and additions to Esther and Daniel are the deuterocanonical books of the Bible. 
New Testament.
The Clementine Vulgate and the original Douay Rheims Bible also included in an appendix three apocrypha books; Prayer of Manasseh, 3 Esdras, and 4 Esdras. 
Canon law.
In another sense, a "Catholic Bible" is a Bible published in accordance with the prescriptions of Catholic canon law, which states:
Divine Revelation, in the form of the New Testament, serves as a source of canon law.
Principles of translation.
Without diminishing the authority of the texts of the books of Scripture in the original languages, the Council of Trent declared the Vulgate the official translation of the Bible for the Latin Church, but did not forbid the making of translations directly from the original languages. Before the middle of the 20th century, Catholic translations were often made from that text rather than from the original languages. Thus Ronald Knox, the author of what has been called the Knox Bible, wrote: "When I talk about translating the Bible, I mean translating the Vulgate." Today, the version of the Bible that is used in official documents in Latin is the Nova Vulgata, a revision of the Vulgate.
The original Bible text is, according to Catholics, "written by the inspired author himself and has more authority and greater weight than any, even the very best, translation whether ancient or modern".
The principles expounded in Pope Pius XII's encyclical "Divino afflante Spiritu" regarding exegesis or interpretation, as in commentaries on the Bible, apply also to the preparation of a translation. These include the need for familiarity with the original languages and other cognate languages, the study of ancient codices and even papyrus fragments of the text and the application to them of textual criticism, "to insure that the sacred text be restored as perfectly as possible, be purified from the corruptions due to the carelessness of the copyists and be freed, as far as may be done, from glosses and omissions, from the interchange and repetition of words and from all other kinds of mistakes, which are wont to make their way gradually into writings handed down through many centuries".
Catholic English versions.
The following are English versions of the Bible that correspond to this description:
1The New Testament was published in 1582, the Old Testament in two volumes, one in 1609, the other in 1610. The Old Testament was followed by three Apocrypha books which are in the appendix of the Clementine Vulgate; Prayer of Manasseh, 3 Esdras, and 4 Esdras.<ref>
