"These two large volumes will provide a very good, quick reference -- yes, even more quickly than the Web... Combining the history and photographs with illustrations and key personnel will make users of this source as knowledgeable about extremist groups as there can possibly be in the general population."--ARBA, March 2007
"a large number of groups are represented, many of which are overlooked in other publications... for students doing in-depth research, this up-to-date set would be the one to use." -– Reed Business Information/Reed Elsevier
"Extremist Groups: Information for Students is designed to provide key facts and insight into the history, philosophy, and motivations driving 150 extremist organizations. Although some groups are included for historical perspective, the vast majority remains active in some form today. The groups profiled range from local political activist and special-interest groups, to international terrorist organizations.
What constitutes extremism is usually contentious and often a matter of cultural or political perspective. Some groups actually admit and embrace their extremism as justifiable toward accomplishment of their agenda or goals. Others work hard to present themselves as more mainstream or "activist"groups. Although many extremist attitudes and acts are seemingly unarguable to a large segment of society, it is also fair to note that the charge of "extremism" is an often-used label applied by opponents in order to marginalize or dismiss an organization's philosophical goals."
