NRSV Hardcover with Deuterocanicals by ABS Now get this, not only are there bottom-of-the-page cross-references, they even reference the Deuterocanonical books. Take for example the image I have for you here on the right. It comes from 1 Corinthians 15:14-50. If you look, you will see references to 2 Maccabees, as well as 4 Maccabees. The Deuterocanonical books, themselves, have cross-references linking to both the Old and New Testaments.
