The book "International Committee of the Fourth International" offers a comprehensive analysis of the Trotskyist movement and its international organizations. It highlights the history and current activities of the International Committee of the Fourth International (ICFI), which is active in several countries. The authors, Frederic P. Miller, Agnes F. Vandome, and John McBrewster, utilize high-quality content from Wikipedia articles to present the development and ideologies of the various groups operating under this name. Notably, the connection of the ICFI to the Socialist Equality Party in the USA and the Workers' Revolutionary Party in the United Kingdom is emphasized.
