The only way I've been able to get any type of readable ASCII TEXT
from the .tif's is to do the following for each tif:
convert -density 1200 -resize 40% xaaa.tif -density 1 xaaa120040.tif
Then, OCR it with Irfanview with the KADMOS Plugin Installed.
For the first Page I get the following ASCII:

I don't know if it's even worth it to continue. Some of the page are so
dark
that they don't scan at all. The best ones aren't anything to brag about.
Ideas? Suggestions?
Thanks.
Larry
