Ok time for me to stop just lurking.
Why don't you put all the scanned jpegs on a swiki? I have no problem
when I have a spare 10 minutes retyping a page in, other people can
proof read my effort and make changes. If enough people take a couple of
pages each it should be done in no time ( I have NO idea how many pages
there are, I am being optimistic :-)
Then turn it into a PDF, much smaller than bitmaps.
