Looking for Konemann's Culinaria series cookbooks

I collect international cookbooks, and I think that Konemann's
Culinaria series are among the best. They're also impossible to find,
either in English or in the original German. Does anyone know why?
Are they no longer being printed? Most books in the series seem to
have been published in the past couple of years

I'm looking for the following books:

Culinaria: Germany (ISBN 3829026218)
Culinaria: Britannia & Eire (ISBN 3829040857)
Culinaria: Greece (ISBN 3829064861
Culinaria: India (ISBN 3829041519)

I saw the Germany book in a store a while ago, and I could kick myself
for not having bought it. I've never seen the other three--I learned
about them through web searches--although they were supposedly
published in 2002.

Any help would be greatly appreciated!
