The images of the ships manifest appear to be in backwards order. Why is that?
Approximately half of the rolls were scanned in backwards when the images were put on the Ellis Island website. The link that you click on to get to the ship manifests will always take you to the lowest-numbered frame for that ship, regardless of how the roll was scanned. For backwards-scanned rolls, that will be the last frame rather than the first for that ship arrival. That was done so that users can get to the remaining frames for that arrival by advancing the frame numbers, regardless of which direction the roll was scanned. Otherwise users who did not know that some rolls are backwards would advance once and then think that there are no more frames for that arrival.
