Books about Harry Potter

[elady25]

I was at Borders today and saw a book entitled "Harry Potter and 
Philosophy (If Aristotle ran Hogwarts) edited by David Bagget and 
Shawn E. Klein.  I was wondering if anyone out there had read it (or 
written it!) and if you thought it was any good.  Also, are there any 
other books *about* the Harry Potter series that deserve a good read 
(other than those by Galadriel Waters).  Thanks!
