I agree that there should be a meaningful short synopsis, but even if there isn't and someone really wants to know what it's about, they can look at the long synopsis which would hopefully be there. How about stepping back a bit and worrying about the books that don't contain a synopsis at all, short or long, before quibbling with the short ones. And in any case, to reject a book because of the lack of a synopsis would be taking it much too far. Hopefully the books will contain the desired synopsis, but if not, the validator is perfectly free to remedy the situation. Pam
