The layout is in single-column, with verse numbers on the margins, just like the recently released Baronius edition. It includes all the notes composed by Msgr. Knox, as well as the cross-references. There is really nothing else included in this compact Bible, which is fine.
One day, I would really like to see the leather edition of this compact New Testament. Until then, I have found this handy little paperback edition to be very helpful for devotional reading before Mass, as well as during our Sunday family rosary. With the uncertainty of ever seeing a compact Knox from Baronius Press, this may the best option out there.
"Such was the history of Nicanor; and since that time the city has been in Jewish possession. Here, then, I will make an end of writing; if it has been done workmanly, and in historian’s fashion, none better pleased than I; if it is of little merit, I must be humoured none the less. Nothing but wine to take, nothing but water, thy health forbids; vary thy drinking, and thou shalt find content. So it is with reading; if the book be too nicely polished at every point, it grows wearisome. So here we will have done with it." --2 Maccabees 15:38-40
