Unfortunately, there have been enough abductions, hijackings and political hostage takings to necessitate The Encyclopedia of Kidnappings, a reference volume encompassing major (and sometimes minor) kidnappings throughout history. Michael Newton (Encyclopedia of Serial Killers) allots brief entries to victims, kidnappers, locations and relevant law enforcement bodies. The Iran hostage crisis, the Lindbergh baby, and Leopold and Loeb are covered, but the book also relates the 1855 kidnapping of an Arizona rancher's daughter by Mexican outlaws, the abduction and murder of Emmett Till, and numerous Eastern European "skyjackers" trying to flee the Soviet bloc. The four paragraphs on "DISAPPEARED, THE" covering Argentina, Chile and other countries can only suggest the grief and devastation wrought by thousands of political murders.
