Is 'The Island of Sheep' out of copyright internationally?
According to
http://onlinebooks.library.upenn.edu...?id=olbp35161:
"The title you have selected (The Island of Sheep) is a post-1922 publication by an author who died more than 50 years ago. Such titles are in the public domain in many countries, particularly those outside the US and Europe. However, 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."
The book isn't on the PG site; but is on PG Australia.
