Reger (Oakland U., Michigan), Myers (U. of Notre Dame) and Einwohner (Purdue U.) edit these academic papers on how individuals maintain their identity in social movements, using case studies that include Jewish resistance fighters in Nazi- occupied Poland and online white supremacy groups. These essays, written primarily for sociology students and practitioners, examine the thought processes that push individuals away from independent thought in order to function as part of a whole and achieve certain goals. Examples are also presented from feminist movements, labor unions and gay/lesbian coalitions. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
