If you like real books and would like to have a printed version of this book in your bookshelf, this is the place to to get one! The first edition was printed by a local printing company in Austria and is sold out. For the second edition I switched to a print-on-demand service (since my local printing company closed a while ago).
You can order a copy of my book directly at lulu.com.
(The price reflects the minimum price I could set there to make it as affordable as possible).
