Advanced AWK Sources

I'm looking for a source on advanced AWK programming beyond the
SUN manuals or generic unix users guides. I would really like a
big thick book with lots of examples.
Any suggestions or recommendations ?

There's an O'Reilly Nutshell book on sed and awk, that should contain
plenty of examples.

PS Sorry for replying in public, but the return address isn't very helpful.
