Its publication, ''Socialist Action'', was produced several times each year. Its pamphlets included ''Abortion a Woman's Right!'' (1975) ; ''The Labour Party'' (1976) ; and ''Revolution in the Americas'' (1981).http://content-backend-a.cdlib.org/view?docId=kt900021c7&doc.view=entire_text It engaged in entrism in the Labour Party after 1976, and merged with the International Marxist Group in 1982.
