Book excerpt: Utopian ventures are worth close attention, to help us understand why some succeed and others fail, for they offer hope for an improved life on earth. Utopias and Utopians is a comprehensive guide to utopian communities and their founders. Some works look at literary utopias or political utopias, etc., and others examine the utopias of only one country: this work examines utopias from antiquity to the present and surveys utopian efforts around the world. Of more than 600 alphabetically arranged entries roughly half are descriptions of utopian ventures; the other half are biographies of those who were involved. Entries are followed by a list of sources and a general bibliography concludes the volume.
