Read 1493, the followup to 1491, by Charles Mann - I didn't think it was quite as interesting - it's a very, very broad examination of globalization as starting with columbus. A few interesting moments that one doesn't normally think of as 'Globalization', like Japanese in 17th c. Mexico and the like, but overall it felt more like a loosely connected series of long articles that something entirely coherent.
Got around to Bloodlands too (Timothy Snyder) , and found it depressing and annoying. Boils down to a really long list of dead people. The argument, as far as i can tell, is that being Ukrainian in the 30's and 40's really, really sucked. OK, I agree.
Berlin Baghdad Express, by Sean McMeekin, about the German-Ottoman collaboration during ww1. I loved it, but then it's about trains and the Ottoman empire and ww1, all together, ie, all my non-fiction crack subjects. Includes actual examination of the hilliness of the Ottoman empire. Could have used more on the actual train, but fascinating anyway.
