Reference numbers used by Whitney to identify an arrangement are recorded in the descriptive field "Item no. (creator)".
The series is arranged into two sub-series. The first, "General files" consists of files that document multiple compositions and arrangements (e.g., files of scores, lead sheets, parts for specific instruments). The second, "Files by song title", consists largely of files that regroup sheet music for a single composition or arrangement, although some files document groups of songs (such as medleys).
Dates of creation note:
Dates are not indicated on the vast majority of documents in this series. In such cases, estimated dates of creation have been recorded in the descriptive field "Dates".
