Is it possible to find out if a translation exists? Books since 1966 have an ISBN (International Standard Book Number), so a book can be traced to the publisher, and then in theory to the copyrightholder, who should than have knowledge of various translations. For public domain books, there is probably historic data on translations. Who keeps track and how of translations after the book entered public domain, I have no idea.
Is any of this information public somewhere?
In this specific case I am trying to find out if a Dutch translation exists of the Croatian book 'Price iz Davnine' by Ivana Brlic Mazuranic. This book was first published in 1916, and has been translated to several languages.
