[Sugar-devel] De-yellowing page images?

I'm asking this question here because at the moment I don't know where
else to ask.  The question relates to the Reading And Sugar book I'm
doing.

I'm scanning in book pages of a book printed in 1928.  The pages are
quite yellow, but readable.  A sample is at:

I'd like to lighten or remove the yellowing from the pages to make the
book more attractive.  Maybe leave the text alone and replace
everything else with white.  I tried different things with GIMP
without much luck.  Any ideas?

Thanks,

James Simmons
