Copies of the final Harry Potter book have already been shipped to customers by one U.S. online retailer, U.S. publisher Scholastic said on Wednesday, and purported copies of the novel have flooded the Internet.

Scholastic Corp. said it was taking legal action against book distributor Levy Home Entertainment and DeepDiscount.com for breaching an embargo preventing the seventh Harry Potter book from being sold in America before 12:01 a.m./0401 GMT on Saturday. The publisher said Levy delivered the books to the online retailer.

People started receiving copies of “Harry Potter and the Deathly Hallows” on Tuesday, but the number of copies shipped only made up “around one one-hundredth of one percent” of the 12 million copies due to go on sale, Scholastic said.

Photographs have also been posted on the Internet of what is claimed to be each page of the book, but Scholastic would not comment on whether they were real. Links to the pictures quickly flooded Web sites around the world.
