It would probably be better, given the involvement of the Official Charts Company (love them or loathe them) to add the information into the OCC website. "Charting" is only a limited, calculated thing, the greater information is the t)ranscribed notes etc of the discs that lesser sold, if we dont have such info from news sheets or fly sheets or printed catelogues (I am certain for example the Pre War REGAL cat must have been printed from tabulating cards)
