Wow, does this take me back to college days. The researchers could never have gone this indepth back then. It was all original sources but with organization limited by no computers. I remember choosing NOT to go into research looking at the work my prof was doing trying to identify anonymous sculptors of the statues on the outside of a cathedral by examining the payroll records of the quarry workers delivering the stone to the cathedral. I hope he lived long enough to see the future of this type of research.
Wow!
