The most recent list we received indicated these were all "life +50"
countries for copyright expiration:

Angola, Argentina, Australia, Bahrain, Bangladesh, Barbados, Belize,
Benin, Bulgaria, Burkina Faso, Burundi, Canada, Chile, China, the Czech
Republic, Egypt, El Salvador, Fiji, Ghana, Iceland, Indonesia, Japan,
(South) Korea, Latvia, Lebanon, Malawi, Morocco, Nepal, New Zealand,
Oman, Pakistan, Panama, the Philippines, Poland, Qatar, St. Vincent
and the Grenadines, Saudi Arabia, Singapore, Solomon Islands, South
Africa, Taiwan, Thailand, Togo, Tonga, Trinidad and Tobago, Tunisia,
and Ukraine.

Works which are in the public domain in Australia and other "Life +50"
countries may remain copyrighted in other countries. People may not
download, or read online, such books if they are in a country where
copyright protections extend more than 50 years past an author's death.
The author's estate and publishers still retain their legal and moral
rights to oversee the work in those countries. That still leaves a lot
of readers out there to enjoy etexts of some of the greatest literary
works of the twentieth century.
