In book 1 the official stool used in the sorting ceremony had 4 legs,
in book 2 it only had 3. In addition I had thought I had discovered
another rather more serious error in book 3 that JKR had made. I
figured the Marauders Map should have showed two different versions of
Harry and Herminie when they went back in time. I was just about to
write to this group and proclaim my brilliance when I discovered JKJ
had made no error at all and I wasn't nearly as smart as I thought I
was. The thing is, I found this recall notice from the manufactures of
the map:      

"A Time Turner exploits a buffer overflow error in the original
Marauders Map that can produce to misleading information. This is
because when the map was first made the manufactures had never heard
of a Time Turner and had not made provisions for it, we apologies for
any inconvenience this may cause. Marauders Map version 2.0 and above
does not contain this flaw; owners of older versions should install
the security patch provided by Messrs Moony, Wormtail, Padfoot, and
Prongs, Purveyors of Aids to Magical Mischief-Makers for over a decade."
