Nope. 95 years past first publish or 70 years past author's death. See the
Wikipedia entry.
So anything published before 1923 is definately in the public domain. Because of the law changes over time, things created after that are may be in the public domain (it depends on whether they renewed their copyright). Starting in the 1950's (I think), it becomes more difficult to know if it's in the public domain or not.
Note that all works created by the U.S. gov't are supposed to be public domain upon their creation.
