The file consists of a minute book, June 1916 - December 1919, of the 'New, Era - Union Men's Sunday Afternoon Class', which was a class for ladies and gentlemen interested in social and industrial problems, and later became a class in industrial history. The minute book also appears to record meetings of the Abertillery branch of the ILP, and the Socialist Labour Party Abertillery branch, in which Ness Edwards was present in 1918. Matters discussed include Rhondda Socialist Society and the Rhondda Plebs League, [Abertillery] unofficial reform league, the Workers' Dreadnought edited by Sylvia Pankhurst, the miners' council, anti-parliamentarianism, the Communist Party, and the People's Russian Information Bureau.
