A rollography is a systematic listing (traditionally a book) of all known music rolls intended to form an authoritative guide to the subject, and usually includes history and artist biographies.  A catalog or list usually shows only the data of the label on the music roll.  A discography is like a rollography except it's concerned with music box discs (or phonograph records).  See the discussion "Data Base Rollography or Catalog" by librarian Matthew Caulfield.
