No word yet on when the next Harry Potter book (search) comes out, but at least there's a title: "Harry Potter and the Half Blood Prince."

"Well the door opened at last and I showed you the title of book six -- the genuine title, the title that will appear on the published book, the title I have been using in my head for ages and ages," author J.K. Rowling wrote on her Web site.

The British author's U.S. publisher, Scholastic, confirmed the title on Tuesday.

A previous posting on Rowling's site, listed under "Gossip," had led some fans to believe the book would be called "Harry Potter and the Pillar of Storge." Rowling dismissed that title as laughable.

The most recent Potter book, "Harry Potter and the Order of the Phoenix," (search) was released last summer. The paperback comes out Aug. 10 with a first printing of 2 million.
