Hello Cathy,
you have already helped me a lot so far. Thank you very much, I highly appreciate it!
I'm going to call AKdFF e.V. tomorrow. Actually, their office and the library are only three hours away from me by car.
However, not easy to arrange with family - also because of the libraries opening hours.
There's also something on the website regarding renovation work and limited access.
We'll see. I hope it works out.
Best regards,
Dominik
