Any copies of articles, magazines, unpublished reports, or even field notes about caves in general and Namibian caves in particular will be greatly appreciated. Duplicate copies of articles on Namibian caves are distributed to the National Archives, National Reference Library, and the libraries of the Namibian Geological Survey and the Namibia Scientific Society.

Visitors should take note that a permit from the Namibian Mining Commissioner is required to export mineral, rock, and soil samples. Some cavers gag at the ammonia smell of bat urine.
