[Kraftwerk] Albert Koch's book: "Kraftwerk"

Last weekend i bought a book from Albert Koch with the titel "Kraftwerk" (ISBN: 3-85445-213-6). This book came out in 2002 in the serie "The Music Makers" at the Hannibal publishing company. "Hannibal" is the same company where Flür brought out his book in 1999 "Kraftwerk - Ich war ein Roboter". The man in the bookshop told me that the selling of the book will be stopped soon. No more copies are available at the publishing company. Does anyone of you know the reason for this? Is it the same story as with Flür's book where R&F stopped the selling? Jürgen
