OT: A good book on Applescript?

[Kurt Kaufman]

Try "Applescript, a Definitive Guide" by Matt Neuburg (O'Reilly, 2004). 
  Many of the older available AS books are geared towards Applescript as 
it functions in Mac OS 9.

I know that there are at least 2 other recent Applescript books, but I 
have not seen them yet:
  	"AppleScript: The Missing Manual"  by Adam Goldstein
	"AppleScript 1-2-3" by Sal Soghoian

HTH, Kurt
