It varies by country.  In the case of the USA, 95 years from publication 
(for older works)  Other countries employ the author's life+x years 
(usually 50 or 70)--live to a ripe old age and your copyright can run 
for a very long time.

In the USA, the rule of thumb is that you're generally safe with works 
published before 1923, which, I imagine does not include much computer
