I guess its named just Mineclonia. You can still try search it here: https://content.minetest.net/
Mineclonia is a fork of MineClone2, last time I tried them, they were quite simmilar (obviously). As far my experience goes, the saves are not 100% compatible (textures broke, but it remembered blocks) and same with the mods, some work, some fail. I would try both.
There's a browser extension for IA books. Haven't tested, but has source on github.
