Very in ways that matter to this board!
lots of words have been changed-- and these words sometimes change the whole character of the scene--

one i remember reading about was "crumpets" to "english muffins"-- and there are so many things wrong with this change.. i suppose you can buy store baked crumpets.. but similar to biscuits in US-- crumpets are fast, and easy to make--and when made well, heavenly.. english muffins, well are nice, but hardly compare.. besides, english muffins get toasted.. and are more often thought of as a breakfast food.. crumpets are closer to what is sometime sold in US bakeries and coffee shops as "tea scone"-- which i always think are way to rich and cake like -- compared to the scones my nana made..
this is one one change... and look what it does-- multiply by a 1000 over the course of the series.. its like reading 2 different sets of books...
