How can I tell which code corresponds to which book of the Bible?
In its databases and downloads, The Unbound Bible uses the following "book index" codes instead of names for the books of the Bible.
Note that book indexes ending in "O" are Old Testament books, book indexes ending in "N" are New Testament books, and book indexes ending in "A" are Apocryphal/Deuterocanonical books.
