I'll aggree that theres lots of improvement on the conceptual level.
Though to clarify the BookInfo module is designed to be more of a
library of how to find the information... for example you could:

foreach my $isbn (@$isbns) {
   $data->{$isnb}->{title} = $BookInfo->get_title($isbn);
}

So in an instance like this it would seem more like a hog to have to
create a new instance of BookInfo just to pass an isbn to get the
title... in instance where you need that thats where Single ISBN comes
in.

Sorry if I did not explain that very well.

thanks everyone for all the responses. I have more then enough to poke
at things with.
