Shayne,
As you mentioned, the "Seven Dispensations" by J R Graves appears to be copyrighted and available in book format only, not digital. Unless permission is received from the copyright holder, putting it in e-Sword format would be impossible.
By the way, Isaiah heard God's Words and prophesied correctly when speaking of today's world. Our only option is to cry out to the Lord, "Here I am. Send me!"... Isaiah 6:8.
May God bless...
