[X4U] Address book data?

[John Daschbach]

In a major error the other day I dragged my home directory onto the  
Shelf in Pathfinder, thinking this would restore the home folder in  
the shelf sidebar (like the sidebar in Finder).  This isn't how you  
should do it, and it "simply" moved my entire home directory and  
everything below it to the target in the sidebar I hit,  
Applications.  It took some time to restore my folders due to  
permission problems, but I got most things back.  However, somethings  
are messed up.  For one, my address book is empty.  Where is the data  
for address book stored?  I'm hoping it will be restorable from  
either the main disk or a backup hard disk, but I need to find it.   
It doesn't appear in a folder of Documents or Library.  Anybody know  
where I should look?
