Some Harry Potter fans may have found it difficult to decipher the boy wizard's latest adventure.
An unknown number of first edition copies of Harry Potter and the Half-Blood Prince were released with upside-down covers and sideways type.
"All the copy on the inside is printed upside down and skewed to the top," said Sorya Gaulin of Indigo Books and Music, who snapped up a defective copy of the book that she discovered in a store order.
Misprints aren't uncommon in the publishing world and even though the few defective copies are sure to draw special attention among the wizard-wild public, at least one collector says they won't amount to much more than a conversation piece.
"Books are bound upside down all the time. Dust jackets are misprinted, there's crooked type," said Burlington, Ont., bookseller Len Shoup.
A spokesman for Raincoast Books agreed that it's normal a few copies in a print run would have some faults, adding the company will exchange any defective copies of the book.
One of the flawed books was for sale yesterday on online auction house eBay, drawing bids of almost $60. The book retails for about $41 in Canada.
Since so many million copies have been printed, Shoup suggested the latest Harry holds little interest for collectors.
"In my humble opinion, any copy of Harry Potter and the Half-Blood Prince that came out Friday night at 12:01 isn't going to be worth much more 30 years from now because there are so many copies," he said.
Some 6.9 million first edition copies were sold in the U.S. over the weekend. More than two million were snapped up in the United Kingdom and Amazon's online book websites sold 1.5 million copies through advance orders. A spokesman for Raincoast said yesterday numbers weren't available for Canada.
A first-printing, first-edition of the first book in the series, Harry Potter and the Philosopher's Stone, might be worth upwards of $30,000 US today, Shoup said.
