The American Association of Publishers (AAP) figures for June were finally released last week (about a month late), and the news is not good for fans of print books. Like the figures for May, all major print categories are down, while e-books continue to surge. But the headline figure this month is that trade paperback sales, which are usually reasonably robust, have just collapsed. The figures in the table below are in millions of dollars. You should note that this month there are just 78 houses reporting print data and only 15 reporting e-data, so the usual caveats apply (although the trends are clear and confirmed from other sources).
