the book belonged to the school (McGonagall says Harry and Ron can use 
the school books until their own books arrive). So it wouldn't been 
his right to do so. I believe that book passed through many hands 
before reaching Harry's.

Magpie:
I don't see how this book doesn't belong to Snape. It says right 
inside: This book is the property of the Half-Blood Prince--Snape. The 
students buy their books, even if it's second hand or handed down to 
them from family. Hogwarts isn't like, for instance, a lot of high 
schools where they hand out books at the beginning of the year and 
take them back.

McGonagall may of course be referring to books that the school has, 
but I think this particular book has an owner.
