Here France has the most number of scientific and educational spoken word recordings regarding caves, which in some ways is altogether fitting as France along with Austria was where serious studies of caves first began in the 19th Century.
      There are also a fair number of spoken word discs mostly released by show caves as a way of promoting their cave. Among these are Australia’s Jenolan Caves, Slovenia’s Postojnska jama (Postojna Cave), several Slovak show caves, Hungary’s Baradla Barlang (Baradla Cave), Georgia’s Novy Afon Cave (New Athos Cave), and for the United States four show caves: Fern Grotto, Luray Caverns, Shenandoah Caverns, Smoke Hole Caverns, plus the Natural Bridge of Virginia.
       Tasmania provides a very special case where the recording has accounts by the original explorer of the Gunns Plains Cave plus tales by those who developed and operated this remarkable show cave.
       Several of these discs are thin flex-discs or postcard discs running at various speeds, which can be difficult to play on a modern turntable. Suggestions are given here regarding certain especially troublesome discs.
       Often the records come in an audio-visual aids package with a supplementary booklet and a series of color slides, but over the years these slides frequently lose their color and turn reddish.
