Well, that usually comes under editors and I have a couple of options
where to enter that info: sub_title or description fields and I can
always add a &nbsp; for author first_name and Various or whatever for
last_name :-)

Thank you guys, for the input. Never thought so many would help so
few(little me). ;-)
I'm really just a little shorter than BG at 6'5" :-D
Actually, I started out and still am with the db normalized. It all
works quite well, it's just frustrating to have to go through all the
contortions to check things. I started out with just checking the title,
then had to add a check to the sub_title, (already have a check for
author) but now have to add another to go with the specific book... oh,
well... all a part of the learning process. :-)
