Barnes & Noble announced yesterday that the advance sales for the sixth Harry Potter book, "Harry Potter and the Half-Blood Prince", topped 750,000 copies, beating the number of pre-orders for the last Potter book.
"The Harry Potter series has shattered all records in publishing history, and the enormous amount of pre-orders to date confirm that the latest Harry Potter title will be the most popular yet," Barnes & Noble CEO Steve Riggio said in a statement.
"In fact, we predict that our pre-orders will top one million."
