James:
There seems to be a spate of the same quetion recently:
There are two principle directories:
CDROMs in Print, by Meckler Press,11 Ferry Lane, Westport CT 06880;
203/226-6967, about $100
The CDROM Directory – 1993, published by TFPL, available in the US from
Pemberton Press, 800/248-8466, about $160
Both are available in print and on CDROM. Hope this helps!
