 Kaczynski has been an active writer in prison . The Labadie Collection , part of the University of Michigan 's Special Collections Library , houses Kaczynski 's correspondence from over 400 people since his arrest in April 1996 , including carbon copy replies , legal documents , publications , and clippings . The names of most correspondents will be kept sealed until 2049 . Kaczynski has also been battling in federal court in Northern California over the auction of his journals and other correspondence . On January 10 , 2009 , the United States Court of Appeals for the Ninth Circuit in San Francisco rejected Kaczynski 's arguments that the government 's sale of his writings violates his freedom of expression . His writings , books , and other possessions were sold online , and the money raised was sent to several of his victims .
