It is the very last edition of "Caves and Caving" (subtitled "Bulletin of the British Cave Research Association"), and is simply dated "2002" but doesn't give a month, so it's not clear when it was actually issued. It is after July 2002, since it has a report of a death in Porth yr Ogof on 22 July, but before September, since it advertises Hidden Earth in Monmouth on 27-29 September 2002.
The Editorial on page 4, written by Paul Mann, states that this will be the last edition of "Caves and Caving" - however there is a note at the foot of page 5 that the next copy deadline will be 20th. December 2002!
Its place was intended to be taken by "Speleology", (also subtitled "Bulletin of the British Cave Research Association"), which began with Issue 1 in January 2003. The subtitle changed with issue 9, April 2007, to become "The Bulletin of British Caving", however it ceased publication altogether with issue 19, December 2013 and has not been replaced.
