Will all the ASV’s footnotes be included?

With the goal of increased simplicity and focus on the English text, ASV marginal footnotes have been reduced to mark only those variants significant enough to warrant attention, i.e. where text is omitted, disputed, or deemed theologically sensitive.  For examples, refer to Matthew 17:20, 18:10, 23:13; Mark 7:15, 9:43, 11:25, 15: 27, 16:9; John 5:3, 7:53; Acts 8:36, 15:33, 24:6, 28:28; Romans 16:23.

Will the ASV’s italicized words be retained?

Yes, absolutely.
