And on to document 3.

Document 3 is readable just if loaded onto the device and put in landscape mode, but it is not ideal.

Reflow works OK for the text part of it -- and indeed, it gets very readable -- but the formatting of the numbered displays gets changed, and it isn't always as clear as it should be.

As I predicted, sopdf was thrown off in its ability to remove margins by the boxes in the corners. The odd thing, however, is that this was a problem only on the lower half of the page. The upper half of the page looks great.

Finally, I did a manual crop of the margins myself and then sopdfed and the result was very attractice and easy to read. A manual crop like this could be time-consuming however. It would be worth it if you were going to read an entire book, but for a short journal article, it might be more trouble than it's worth.

Anyway, I hope that helps.

(P.S. as a logic teacher, some of these were fun to look at for me too...)
