Bonjour,

I am sorry for the silence. But, because some users of the platform wanted to have paperback versions of the PDF that are available, I had to concentrate on this project during the whole month of September. And it was not a simple matter. And I am happy to inform you that there are now 200+ books (of different formats) available on Amazon.com.

If you want to have an overview of all the books, please go to my author page:
