On a cable-modem or DSL connection, it only takes a few minutes to suck 'em
all down.  Putting them in one file makes them easier to grab as a set.

(The Zip format allows files to be stored without compression, which
would've been the better way to group already-compressed files (JPEGs, MP3s,
etc.) together.)

- From what little fooling around I was able to do last night, once the files
are converted from grayscale (8 bpp) to 1 bpp, they should feed into most
OCR packages fairly easily.  I did a batch conversion under Linux, something
like this:

for i in *.jpg; do djpeg -P $i | ppmtopgm | pgmtopbm -thresh -val 0.7 | \
  pnmtotiff >$i.tif; done

Under WinME, I had TextBridge Pro 98 convert one of the pages to text; it
had a few errors, but not so many as to be useless.  The text was dumped
into Notepad, where HTML tags were added for formatting.  It looks like I
have a project on which to work now...:-)
