From the above post: "While it’s unclear if the book industry will ever experience a phenomenon quite like Harry Potter again – the first six books have sold more than 325 million copies in 64 languages, dwarfing even The Da Vinci Code’s 60+ million copies in print – we can be sure that the press will spill many gallons of ink on the end of the series over the next six months or so. And to be honest, it’s probably deserved. There’s never been anything else quite like it."
Exactly. There are already hundreds of articles about the last book in the series, as well as at least two "pre-HP7" books that I know about. As we approach 21 July, there will be a lot more. Then there will be the reviews, the analyses and the postmortems. And the backlash or the glowing reassessment, depending on what position the commentator took last time round.
But at the end of the day, there it is. 325 million people are buying and reading (no "Brief History of Time" effect here) Harry Potter. What a wonderful, magnificent and rewarding experience for Harry’s creator, J. K. Rowling.
