So I found out that this link for a free online course:
http://educate.barnesandnobleuniversity.com/educate/bn/home/catalog/ov
erview.jsp?productId=7940&userid=2UPN50Z1VG&nhid=bn

which requires this book: Beacham's Sourcebook For Teaching Young 
Adult Fiction: Exploring Harry Potter
by Elizabeth D. Schafer, Elizabeth D. Sullivan 
http://www.amazon.com/exec/obidos/ASIN/0933833571/qid=1052884918/sr=2-
3/ref=sr_2_3/104-3678683-5654324

which I didn't find at BNN, but found another: 
Ultimate Unofficial Guide to the Mysteries of Harry Potter by 
Galadriel Waters, Astre Mithrandir (Paperback) 

which is also listed on the first books links, along with:
Harry Potter's World: Multidisciplinary Critical Perspectives by 
Elizabeth E. Heilman (Editor) (Hardcover) 
The Magical Worlds of Harry Potter: A Treasury of Myths, Legends, and 
Fascinating Facts by David Colbert (Paperback) 
The Hidden Key to Harry Potter: Understanding the Meaning, Genius, 
and Popularity of Joanne Rowling's Harry Potter Novels by John 
Granger (Paperback) 
The Sorcerer's Companion: A Guide to the Magical World of Harry 
Potter by Allan Zola Kronzek, Elizabeth Kronzek (Paperback).

I didn't see a post about this when I searched, so excuse me if wrong.

The store lights flashed to indicate closing before I got very far 
checking the one book they had.  Are there any comments on these 
guides by people on this list?

Thanks,

A.J.
