I have an account with Berlin libraries and they offer both Libby and Overdrive (and some others) with a fairly large catalog. There is deDRM for calibre, and a command line tool called Knock which does not require Adobe software to remove the DRM.

Ah nice we don't have anything like that here.

But I don't think I will go back from what I'm doing now. It took a lot to get me to leave Amazon, but the DRM thing and also lately the larger amount of books "not available in your country or region" has just made me give up on the industry.

I will buy books now only if they are available to buy without DRM, and if they are not I will just pirate them.
