Ha! That's a a lot of Robbie Williams!
Textbooks are always growing as a segment, so that's something to look at. We're featuring Wind in the Willows right now, so that can mean some big ticket items where people are looking for firsts. As the Olympics approach, books on both the Olympics, and on China's human rights track record and Tibet will likely pick up as well.
Glad to help out, anyway! Don't hesitate to let me know if you have any other questions.
