#WritersCoffeeClub Jan. 4: Share a tool of your trade.
Digital archives of public domain works, since they provide the German folk tale collections I translate.
The #InternetArchive and Google Books are the most important ones I use, but honorable mentions go out to:
Münchener DigitalisierungsZentrum: https://www.digitale-sammlungen.de/en/
Silesian Digital Library:
https://sbc.org.pl/dlibra
Russian State Library:
https://search.rsl.ru/
all of which have large numbers of German-language books in the public domain as well.
