Xerox Rooms?

[Curt - Atari Museum]

I was looking for some history books on Parc on Ebay and while searching 
I ran across this auction:


http://cgi.ebay.com/Rare-Xerox-Rooms-Developed-By-PARC-NIB_W0QQitemZ200053055800QQihZ010QQcategoryZ1247QQrdZ1QQssPageNameZWD1VQQcmdZViewItem


What exactly is it?     I'm not interested in bidding, maybe someone on 
the list would like it, I would just like to know more about what the 
program did for Windows.
