First time I'm seeing it, to be honest, but it looks interesting. I do plan on having an UI for Librario (built a few mockups yesterday[1][2][3]), and I think the idea is similar, but BookBrainz looks bigger in scope.

I could add them as an extractor, I suppose :thinking:

Doesn't seem to have a very compleat dataset --- the first book I thought to lok for, Hal Clement's _Space Lash_ (originally published as _Small Changes_) is absent, and I didn't see the later collection _Music of Many Sphere_ either:
