A: It's been accelerating over the past 14 months. The past three months we added more than 40,000 titles to the selection so not only are we going to keep growing [it], we're going to keep accelerating the rate at which we're growing the selection. The vision is every book, ever printed, in any language, all available within 60 seconds. That's a big, long, multi=year vision to get every book ever printed, but it is possible and we will eventually do it. We'll just have to be relentless [laughs].
