With the official opening of the holiday shopping season, bookstores are seeing a lift though total sales were well below last year’s holiday kick-off. In outlets monitored by Nielsen BookScan, book sales for the week (through last Saturday) were 15.396 million units–a three percent increase over the prior week, but 9 percent lower than the same Thanksgiving-week from 2008, which registered sales of 16.857 million units.
