Patrick.
It's hard to know whether you mean the whole page is scanned at an
angle, or that the text is badly distorted where the page curves
up into the spine when the book is squashed flat.
If the whole page is at an angle, then imagemagick 'convert' does
a reasonable job of deskewing.
I don't know about software to correct curved text, but I do my scanning
with a Plustek Opticbook scanner. It gets pretty close to the spine
of the book (about 1/4" for my 3600 model) without needing to try
to squash the book flat. So there is pretty well no skewing over
the scanning surface. If you're doing the scanning yourself and
money isn't too tight, you could look into getting one of these
scanners yourself.
