are different translations of the same basic text but with differing numbering systems for the letters. I created a parallel resource collection for them, positioned myself at Letter 19: Ambrose to Vigilius. I opened the parallel resources, selected the other resource and was taken to Letter 35, Ambrose to Vigilius. Quite nice. Thank you.
