This manuscript entitled Istina o Jugoslaviji. Proživio sam dvadeset godina u komunističkoj Jugoslaviji. I. redakcija (The truth about Yugoslavia. I survived twenty years in communist Yugoslavia) was written in Padua in 1970, but printed in 1977 as a book in Croatian under the title Iza bodljikave žice: sudbina Hrvatske u srbokomunističkoj Jugoslaviji (Behind Barbed Wire: the Fate of Croatia in Serb-Communist Yugoslavia). In it, Čolak described his life before going into exile. He explained his life trajectory from the communist prison until the attempt to establish the first free review in Yugoslavia.
