Public Domain Materials

Many works are considered to be in the public domain. In this case either the copyright for these works has expired or the author has decided not to copyright the work. This allows them to be used and distributed freely. As a basic rule of thumb, works copyrighted before 1923 are safely in the public domain. The following is a listing of public domain resources on the interhet. However, you should always check to make sure material on a "public domain" site is really public domain.
