The volumes of the Répertoire International des Sources Musicales (hereafter RISM) devoted to manuscripts of polyphonic music contain a nearly complete catalogue of the sources of late-medieval English polyphony known in the literature at the time of their publication in the late 1960s and early 1970s. Since that time a substantial number of new sources has been discovered or rediscovered.
