I recently discovered that my book, Kylix 2 Development has been translated to the Portuguese language! You can purchase it here.
Thanks to Ronaldo Rezende Vilela Luiz for letting me know about this newest translation.
If you know about other translations, please let me know by adding a comment to this entry or sending me an e-mail to rick at rick dash ross dot com. Currently, Kylix 2 Development has been translated to German as well.
