I'm guessing that .AZW is a proprietary AmaZon(something that starts with "W") format. It seems to me that I did locate an AZW extension for something, but it was totally unrelated (like medical engineering or drafting or something -- sorry, really don't remember

)
I think that Palm executables usually have a .PRC extension, is that what you mean by "Palm Resource?"
The list is a bit short, but not really shorter than the Sony (please don't let me start you on a rant on that, rlauzon

)
