Lehrbuch der Schottish-gälischen Sprache
The course consists of coursebook, CD (long mp3 disc) and teacher's or self-study guide with answers, dialogue translations , further grammar tables etc.
This is a first in Germany, the only other German 'course' being the short phrasebook-like 'Schottisch-Gälisch Wort für Wort' in the restrictive framework of the 'Kauderwelsch' series - by the same author, Michael Klevenhaus ('Mr Gaelic' in Germany

I've had a good look at it and am impressed by the no-nonsense systematic and thorough approach, and the care taken in the 'extras' - wordlists, glossaries, cross-referencing, indexing, clearly signposted dialect variations on the audio recordings etc.
Current standard Gaelic coursebooks in English could safely take a duileag no dhà out of this one, espcially as regards ease of reference via the detailed contents and index pages.
You can get the books from Buske Verlag if you're in Germany, otherwise via Amazon.de

And no, I have no axe to grind!

Just don't like to keep good news to myself!
