I looked at the JP2 images and they look the same as the PDF. It was
in the scanning, probably in the way the grayscale threshholds were
set. They look like photostats.


Thanks. I was hopeful but not surprised. I've done some trial & error
work with scanning and document creation. It isn't a straight forward
process. A lot of the good old material at Archive was done with a
Canon 5D camera and 500dpi. You could see the focus shift (fuzzy) as the
pages were turned and thickness changed sometimes. I guessing but the
operator needed to adjust the focus distance more often...

I can make djvu docs but not of the quality they have. Lizard Tech used
to be the djvu vendor:

It broke my heart when Archive dropped making djvu docs
