Hi Marcie, If you are having trouble you could also try
www.bookwebsites.com/bookcats2.fcgi?path=582!Booksellers:585!Bookfin
der= s
www.antiqbook.com/books/index/phtml (this is a Dutch site)
If you have no luck with that you can always try someone who will do
the search for you. I use an English outfit called Twiggers Books
www.twiggers.co.uk There are a few in one of the web sites I have
given you. They tend to have a lot of booksellers who are not on the
web.
