I'm reviewing this entry:
https://crowd.loc.gov/campaigns/bernstein/coates/2023777634/2023777634-1/
In my opinion I would have put this in the proper reading order and marked the left "page" as marginalia. In other words, I would have started on the right side of the page and ended on the left as it looks like this was folded or started on the right and finished on the left.
What would be correct, though?
