[Question] How to find translations of a book?

What is the best way to find whether a book was translated to other languages (and how are the translations called)?

I assumed that there would be some global database for that; it feels like something that obviously should exist—if you already assign ISBNs to books, the logical next step is to make a database that contains them, plus some metadata, including “this is a translation of this”—but unless I am missing something obvious, there is no such service.

Here is a specific book I was recently looking for, but the question is general:

Author: Владимир Артурович Лёвшин (Vladimir Arturovich Levshin or Lyovshin)

Book title: Три дня в Карликании

So far I only know about translations to Vietnamese and Slovak; the former I found on Wikipedia (the author only has a Wikipedia page in Russian and Vietnamese), the later because I happened to find that one in a library—I couldn’t find out about it otherwise.

(It is a book about math, for small kids. A very good one, if my memories are reliable.)
