There is an effort to extend copyright protection beyond the current 70 years and increase it another 20 years. Guess who is behind this? The Walt Disney company because guess who turns 70 real soon. Its all about money and making sure that nothing becomes part of the public domain. The copyright laws on printed matter used to be 35 years. That seemed long enough but Congress doubled it to 70 a few years ago. That sure seems long enough doesn't it? So now you can only copy books published prior to 1932. Regards, Robert Cowan
