So, I've finished up the old crop, including the second volume by Hobsbawm. My current reading list is:
Nature's Metropolis by William Cronon - It's a history of the city of Chicago. I haven't read much on the history of urbanization since a class I took in undergrad years ago, so I'm looking forward to diving into this one (I'm on page 4 or 5 of the prologue, not much to say yet). The blurb on the back talks about environmental, economical, and institutional changes from the 19th century to today, so it's casting a fairly broad net (which means it will either be a great work of synthesis or a confusing flop).
The Rise of Theodore Roosevelt by Edmund Morris - I first saw this trilogy on The Daily Show, been waiting to read them for some time. The first book covers Theodore Roosevelt's childhood and early political life, which is what I'm reading now. I probably could have skipped this book given that I'm more interested in his presidency (which is the subject of the second volume), but it is interesting enough that I'm sticking around. Plus, he was involved in the Republican convention that put up James Blaine and later the Secretary of the Navy, Governor of New York, and Vice Presidency in rapid succession, not to mention that stint with the Rough Riders... I think there's a payoff coming.
