US and UK editions

[Belinda]

On the index page of the HP Lexicon, 
on the righthand side of the page, is a list of links within the site.
Look for British/US Editions.
This will take you to a page detailing ALL the changes and differences 
in the editions for each book.  As you will see the changes have 
become much fewer in the more recent editions.


(I'm assuming you have heard of the Lexicon, if not, post again, and 
I'll give you the address :-)
