If you do not have any pages with all links listed, 
you'll have either to create one, or create an URL list

Create a list.txt file :

<http://foobar.com/la/livre0001.html>
<http://foobar.com/la/livre0002.html>
<http://foobar.com/la/livre0003.html>
..

Then use the "URL list" feature of HTTrack to download 
all links

The list can be created using some batch like script:

i=0; while test "$i" -lt 10000; do L=`printf $i|wc -
c`; L=$[4-$L]; Z=`echo 0000|cut -c1-$L`; 
echo <http://foobar.com/la/livre$Z$i.html>; i=$[$i+1]; 
done
