There is not much system in the way works derived from Bach's compositions are listed. The "R" addition to the BWV number is only well-established for the reconstructions included in NBA VII/7 (e.g. solo violin reconstructions of BWV 565 are not usually indicated as BWV 565R, neither is the system used for reconstructed vocal works). For some series of transcriptions and arrangements works catalogues of these transcribers/arrangers may hold sublists with works derived from compositions by Bach.
