“Not necessarily – the archives staff could have made copies for the reading room of the originals with the hand-written notes.”

Good point, R C. But even that raises questions too. Did they make copies of ALL documents with notes? Which ones? When were the notes made? And was Berger aware of their being copies (if there were)?

No wonder this investigation is taking so long. It is indeed more complicated than it appears on the surface. And more important.
