These two significant journals on research in speleology were published by Cave Research Associates during the period 1959 to 1973. Since 1975 issues had been unavailable. Former members of Cave Research Associates donated uncirculated issues of the journals to the Tumbling Creek Cave Foundation. The Foundation reprinted a few missing issues and made complete sets that are now available in three hardbound volumes. The sets are available from the Foundation for $200 plus $5 shipping and handling with all proceeds to aid the Foundation. Buy a set, help the Foundation, and keep important studies available.
