For obvious reasons, reliable and up-to-date material on terrorism and counter-terrorism is less available than for many other types of crime. The Office for Security and Counter-Terrorism is a department of the Home Office and is a source of policy documents and some statistical data. A more independent source of information and with a wider view is the long established Handa Centre for the Study of Terrorism and Political Violence at St. Andrew's University). See also work conducted by the Royal United Services Institute and the International Centre for Counter-Terrorism in the Netherlands. The National Consortium for the Study of Terrorism and Responses to Terrorism at the University of Maryland provides a more global view and is also a good source of research studies in this area.
