New York ? Barack Obama is the hottest name in publishing.

On the weekend after he became the country’s first black president-elect, Obama’s “The Audacity of Hope” and “Dreams from My Father,” both already million sellers, ranked No. 1 and No. 2, respectively, on Amazon.com and Barnes & Noble.com.

Both hardcover and paperback editions of “Audacity of Hope” were out of stock Sunday on Amazon.

Sales are up even in Arizona, home state of Obama’s Republican opponent, Sen. John McCain.

“People are generally much happier this week than they were last week,” Gayle Shanks, co-owner of the Changing Hands Bookstore in Tempe, said Sunday.
