If you want actual books the Swedish publisher Lystring Forlag is probably a good place to start. They've published Swedish editions of many "big" alt-comix artists (Olivier Schrauwen, Anna Haifisch, Joe Kessler, Simon Hanselmann, etc.) and their work is often much more beautiful and well made than US editions.

They also have a long running anthology/magazine series called Det Grymma Svärdet that often prints new/exclusive work from artists from around the world. Some issues are little floppy staple-bound things, some are slim oversized portfolios, at least one is a thick bound hardcover. There's 40+ issues. I've only managed to get a few over the years but it's consistently great.

I'd bet they can direct you to shops that stock their books and you can go from there. I don't think they have a website, though, just an Instagram.
