Why we'll never know all about the WW

One thing I've noticed is that people sometimes forget that the HP books 
are about Harry Potter and that if something doesn't come to his attention, 
we usually won't know about it. Also, if something comes to his attention 
and it's not related to the story, we are still unlikely to know about it.

The HP saga is so huge, that JKR has to leave out nearly everything that 
isn't directly related to the story. That makes finding clues a little 
easier, though, since if a mention of something isn't significant in the 
current book, odds are good that it's a "foreshadowing" of something in a 
future book.

Think about it! If it was all in the books, they'd be at least as large as 
a set of encyclopedias!

That's not to say that it's not fun to speculate about and recreate JKR's 
wizarding world using hints from the books and their author. It is fun! But 
because the story is centered on Harry, we should expect that some of the 
peripherals won't hang together properly.
