A number that jumps out is the 36.5 percent increase in audiobooks for September, 40.1 percent for the year. E-books were also up substantially, 27.7 percent for the month, 23.6 percent for the year. I have to think that the audiobook numbers could be related to Christmas shopping, but I have trouble with the idea of an e-book download as a Christmas present. Kinda hard to wrap it up and put it under the tree.
GalleyCat points out that the Kindle could have a real impact on the e-book category!
