Reference Chambers !! If you look at the introductory page of this Rainbow quiz and all the other previous ones, you will see that their recommended Chambers is CHAMBERS ENGLISH DICTIONARY (1990) "our main, but not sole, source of reference for definition " I have a 1998 one which seems to work indeed it is invaluable but I would be interested to obtain a second hand copy of the actual one listed. One could then be absolutely sure of ones answers ! Anybody know where I might obtain the real thing ?
