• Audio* description: Marking of the rollers: Börnstein Bismar[c]k Arch. or Börnstein Südsee. In the original documentation only 108 rolls are mentioned. Another numbering counts until 190 (see postcard to Hornbostel from 1914: 6 Tins - 108 Walzen - 190 Phonogramme). There are many cross-references under the numbers. Correspondence available. Many of the rollers are transcribed by Hübner and Schneider. For collectors and collection see also Niles 2001. The open questions could not be clarified so far.
