I purchased the 10 vols. dictionary "Handwörterbuch des Deutschen Aberglaubens" (1927-1942) on folk beliefs, magical practices, and superstition in the German speaking European countries, from the Middle Ages to the end of the 19th century. Very expensive (*sigh*) but an unrivalled source (*wow*) in very good condition (*yay!*). https://gnusocial.net/attachment/f133de277d47c179628aad03ba55d9287b07d6500f829850879f0465e4e83e69/view
