The total sales volume for 'The Casual Vacancy' over the first six days are here

According to the Hollywood Reporter, the new adult novel by author J.K. Rowling, The Casual Vacancy, has sold 375,000 copies in the all formats (print and digital) over the first six days. For a J.K. Rowling book, this is exceptionally low but the publisher, Little, Brown and Company, is happy.

According to Michael Pietsch from the publisher's office, "The Casual Vacancy has exceeded our expectations in its first six days in stores. We believe it is on track to become the year's bestselling novel in hardcover."

However, if The Casual Vacancy is going to attain that title, it will need to sell a LOT more books to overcome Fifty Shades of Grey, (which debuted in paperback) and No Easy Day (non-fiction).

In the U.K., there were 124,603 copies sold in its first week to take the top spot on the country's fiction chart. This is the fastest-selling hard cover in Britain since Dan Brown's The Lost Symbol came out in 2009, which sold more than 550,000 copies in its first week.

To give you an idea of the volume of books sold by Ms. Rowling in the past: when Harry Potter and the Deathly Hallows was released in 2007, over 8.3 million copies were sold in the first 24 hours. That may be a record that will never be broken again.
