Another book is called "The Winning Way" by Bruce Pandolfini (Fireside Chess Library).
This book contains 150 examples of opening traps, and is indexed by (1) Opening and (2) tactics.
I only picked it up recently, so I haven't gone thru it yet...
Pandolfini also wrote a couple of "Chess Openings - Traps and Zaps" books - there are at least two such volumes out there.
Ooops, I just noticed that your question deals with info on the net, not in books...sorry bout that!
