To our valued customers,

Monday is the day:

Beuth Verlag will become DIN Media.

You can find out more about our new name and the reasons behind it here.

We ask for your understanding that, due to this change, we will be temporarily unavailable on Sunday. It will also not be possible to place any orders on Sunday.

But we will be there for you from Monday onwards with our new name.

Yours sincerely,
Beuth Verlag
