The group includes files of miscellaneous accumulated material relating to the Communist Party, Welsh affairs, devolution, the labour movement, social issues and miscellaneous subjects. They include material produced by the Communist Party Great Britain or Communist Party Wales District, and also documents relating to particular subjects of interest. Some may be research files created by Bert Pearce while preparing an article or leaflet. Most of the files contain information relating to a variety of subjects and only the most significant subjects are noted in the description. They may also occasionally contain minutes of committee meetings, election leaflets, information leaflets, publications, magazines, reports, correspondence, or notes. The dates are often wide ranging since they contain accumulated documents and publications relating to a subject.
