Series CP/CENT/CONG: According to the rules adopted in 1943, the national congress of the CPGB was the 'supreme authority' of the party and responsible for laying down the 'general lines' of its work. Delegates' notes on party congresses, like those of its leading committees, can again provide a useful source of supplementary information, although the more open character of these events and their occasional nature meant that it was often feasible and acceptable to provide full stenographic reports. Along with a mass of related documentation, there are full reports of all congresses from the 20th (1948) to the 28th (1963). For all earlier congresses, beginning with the First Unity Convention in 1920, printed materials are variously supplemented by circulated reports and congress materials, delegates' and observers' notes and press cuttings. There are also full proceedings for the CP's 15th and last pre-war congress, held as a symbolic protest in Chamberlain's home city of Birmingham in September 1938. From 1973, proceedings were tape-recorded and the tapes, along with other sound materials formerly in the CPGB archives, are now deposited with the National Sound Archive. Stenograms of earlier congresses will be found in the Moscow archives. In between the more turbulent affairs of the 1920s and the 1980s, one could have wished that party congresses had been less meticulously choreographed. There were, however, moments of tension, as in 1945, 1956-7 and increasingly from 1968 as party unity ebbed. For the values, the rituals, the language and the political culture of British communism, as well as insights into a wide spread of party activities, the congress materials provide an important source.
