Wahl-O-Mat kann heruntergeladen werden bei der Bundeszentrale für politische Bildung (deutsch, und deutsche Parteien).
A program (script) downloadable from Bundeszentrale für politische Bildung helps you decide which (German) party to vote for in the EU elections on June 13th (questions are in German).
The Bundeszentrale has an excellent collection of publications (in German) that we used to order for students, and many of which can be downloaded nowadays. For instance, there was one issue – it was a magazine – on the UK and one on the USA, full of maps, history, tables, all kinds of background information. If there was one on the German legal system, or German criminal law, I would write off for a set for the class, and they were free of charge for schools. I’m referring to Informationen zur politischen Bildung; there are other series and other publications too. Have a look around the site. I actually thought some of the graphics were online, but I can’t find them now.
