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.
Demand also has surged for "Change We Can Believe In," a collection of Obama's speeches and policy proposals that had been selling modestly; for "Barack Obama in His Own Words" and for such works about him as "Barack Obama: Son of Promise, Child of Hope," a children's book by Nikki Grimes, and Robert Kuttner's "Obama's Challenge," a call for a sweeping, progressive economic agenda.
