Hi !
Hm - I bought the first "Harry Potter" when I was on holiday in scottland... and I can say, that the title of the book was "...and the philosopher's stone" !!! and also in the hole book it was called "philosopher's stone"....
I can't imagine why they changed the title...
And the german title is "...und der Stein der Weisen", what means "...and the stone of the wise"... ;-(
happy Easter
