Each volume contains biographies of individuals and organizations on the "radical left," as determined by the right-wing author's perspective. Period covered extends from the 19th century to the anti-Vietnam War movement. Although the original intention was to publish eight volumes, only four appeared. Gannon was in the John Birch Society's "research department" (sic).
