Copyright
As an article from Duke University Law discusses, a number of important works published prior to 1976 would be entering the public domain this year, including Fahrenheit 451, The Crucible, Second Foundation and others (see the article for some others). I say would have. Prior to 1976, the maximum term of copyright was 56 years (see here (Wikipedia)). In 1976, Copyright was extended to life of author plus 50 years (see preceding link again), including a retroactive extension of copyright to works published before 1976. In 1998, copyrights were extended again by the Mickey Mouse Protection Act, which extended copyrights to life of author plus 70 years, or 95 years, whichever was shorter. Again, this included retroactive extension. Many of you may agree with me that this is silly and needlessly lengthy. Bradbury, Miller, Asimov and others are hardly benefiting from copyright restrictions on their works. They're all dead.
