Catholic Bible

My friend Joe grew up Catholic. He has been reading throught the Bible and journaling with me, but wants to add the books found in the Catholic Bible. There are seven extra old testament books. He had given me a New American Bible, but I have misplaced it. He called me today and gave me this link to the Bible online. USCCB - NAB - Canonical Index

My plan is to go ahead and read these extra books with Joe. It isn't an endorsement by me as a Protestant as to the authority of these books. It is a commitment to my friend and to God to see the significance of these books.
