Good list. It does not include "Silk Roads" by Frankopan, which I agree with. That's a good read but much more a history of world trade (hence the plural) and strangely western-centric. I saw strangely because in the introduction Frankopan says he wanted to write a history from the point of view on central Asia, but its not that at all. Dalyrymple's "Golden Road" succeeds at Frankopan's objective and I found it much better in general. I don't want to sound too negative on "Silk Roads" but I think the title is subtly misleading if you want to learn about the trade general referred to as the Silk Road.
