Like the first (2003) edition, Encyclopedia of Terrorism is intended to be a selective reference work on the most significant aspects of modern world terrorism. The revised edition reports on the major changes to the terrorist groups, which include their splintering, networking, and reforming across national borders. In addition, as terrorism has changed, so have the agencies, policies, and various international organizations that combat its spread. This edition is similar in length and scope to the first, having more than 300 A–Z entries ranging in length from a few paragraphs to several pages, each concluding with references. The entries cover people, such as Idi Amin, Saddam Hussein, Kim Jong Il, and Salman Rushdie, and groups, such as the Haganah, the Japanese Red Army, and the Montana Freemen.
