List elves, kindly forgive what is to follow.  It's not OT, really, 
but I recognize that it is my airing of a pet peeve.  

We all boo-boo from time to time--heaven knows I've deleted a fair 
number of my own posts here and have been red-faced over errors in 
logic--but if I might, I would like to point out the following:

cannon - a large, artillery gun, usually on wheels; a firearm for 
discharging heavy shot with great force

canon - sanctioned or accepted body of related works; the authentic 
works of a writer

JKR has produced a canon, not (as far as we know) a cannon.  :-)
Please forgive if this sounds pompous or snarky; it's not intended 
to.  Just a friendly neighborhood Public Service Announcement.
