_Countering the New Terrorism_, a new 153-page book published by RAND, has recently been made available online. The book contains four chapters that address the changes, trends, and implications of the new terrorism. The introductory chapter, written by Ian O. Lesser, overviews the changes in terrorism in a changing world. The second chapter, "Terrorism Trends and Prospects," by Bruce Hoffman, looks at trends in international terrorism. Chapter three, "Networks, Netwar, and Information-Age Terrorism," by John Arquilla, David Ronfeldt, and Michele Zanini, examines the special problem of terrorism in the information age. The final chapter, "Countering the New Terrorism: Implications for Strategy," also by Lesser, suggests how to meet terrorist challenges to US interests. The book also includes three figures, one table, an index, and a foreword by Brian Michael Jenkins. Each part of the online book is provided as an individual .pdf file.
