But it works both ways: Project Gutenburg has Canadian and Australian sites, and some of their books can't be downloaded thanks to Copyright laws.
this title most likely remains copyrighted under United States law, where works copyrighted in 1923 or later can remain under copyright for up to 95 years after publication. It may also be copyrighted in European Union countries and other countries where copyrights can last longer than 50 years past the author's death.

he is more famous for A Town Like Alice, and his classic anti war film, On the Beach.
