A volunteer has translated the book The Case for Copyright Reform into the Serbian language. You can download the Serbian version here, in either Cyrillic or Latin script. (The English version is of course still available as well.)
The Case for Copyright Reform is free for anybody who wants to translate, adapt, and share in any way you want (Creative Commons CC0). If you make a translation, please feel free to send me a copy (if you want), so that I can make it available on copyrightreform.eu.
The Serbian translation was made by Staša Sihrovski, who is a certified court interpreter for English.
