BBC WAC ref. R9/3: These supplements cover the period December 1945 to October 1952. Their purpose was, as stated at the head of the first one issued, because "The total number of panel reports issued each week has now increased to a point which makes it impracticable to include a list in the body of the LISTENER RESEARCH BULLETIN [BBC WAC ref. R9/1]. It is, therefore, proposed to issue a weekly SUPPLEMENT which will show, under the service of origin [e.g. Home Service], the names of all broadcasts covered by panel reports during the week with which the BULLETIN deals, together with the appropriate Barometer Figure, the Appreciation Index (revised basis), and report number. For more on the context of these bulletin supplements, please see "The good servant: the origins and development of BBC Listener Research 1936-1950"
