I found this book on WorldCat through interlibrary loan – it hails from the University of Michigan Hatcher Graduate Library. Although it appears in name on Amazon it isn’t available for purchase. A Google search also brings up very little – and it appears that there are few printed copies available. It is written in an strange tone – which could be a translation issue – but nonetheless makes me wish I knew more about its origins and the author. The text reads like something between journalism and not propaganda exactly, but carefully supportive of the government perhaps? The only thing I can find about the author is that he is a journalist at the Raksmey Kampuchea Newspaper – which according to Wikipedia – Rasmei Kampuchea (Light of Kampuchea) is Cambodia’s largest daily newspaper. It circulates about 18,000 copies every day in the Khmer language.
