I've spent a fair amount of time searching on-line and not found many zines or zine distros in Germany. I found quite a few at Cafe Nixda in Mainz in 91 when I was a student there. They even had their own zine "Dichtung und Wahrheit." There're Infoladen in Frankfurt (Arbeitslosen Verband), Mannheim (Juz) and something at the Karlstorbahnhof in Heidelberg - if only I can get some time to go and check these out. For now I'm reading American zines.
