Susanne & Stefan Wagenhals
Lobo Plus (2021) ISBN
A thorough and up to date coverage of the Schwartzwald climbing.
All text/descriptions are in German with no translations and the access maps are fairly poor.
Crag photo-topos are fairly good (this is an area where getting a decent crag photo is really hard!)
