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:

This is great - the service and that you're extending it and considering a UI.

Personally I would go with option 2 as the colour from the covers beats the anaemic feel of 1 and it seems more original than the search with grid below of 3.

Glad you liked the idea!

Number two is what my wife and I prefer too, and likely what's going to be chosen in the end.

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:
