Anarchism is a social and political ideology which, despite a history of defeat, continually re-emerges in a new guise or in a new country, so that another chapter has to be added to its chronology, or another dimension to its scope. In 1962 George Woodcock wrote a 470-page book, Anarchism, which, continually reprinted as a Penguin Book and translated into many languages, became probably the most widely read book on the subject in the world. Woodcock wrote a series of updating postscripts until his death in 1995
