Franz Stoiber has been teaching Hausa for many years at the Department of African Studies at the University of Vienna. He has produced a number of online materials (in German), including:
- a Hausa text book (“Hausa-Online-Lehrbuch“)
- a Hausa Dictionary (“Hausa Online Wörterbuch”)
- a Hausa Grammar Synopsis
There is other linguistics stuff, and some photographs, too. Check out what is there!
