How many books are in Old Testaments?

Catholics believe there are 46 books in the Old Testament and 27 in the New Testament. Most Protestant faiths claim there are only 39 inspired books in the Old Testament but agree that there are 27 in the New Testament. The extra seven books in the Catholic versions of The Bible are called the Deutero-canonicals and include the books of Tobit, Judith, Wisdom of Solomon, Sirach, Baruch, and 1st and 2nd Maccabees. Some Protestant versions of the Bible also include these seven books but they are not considered to be inspired by God and are generally called the Apocryphal Books.
