At least for a historian. Seriously, those guys will raid your garbage bin and steal your receipts. And the humanity will be grateful. After a while. I’ve just put my hands on the last (well, fourth out of five, they weren’t delivered in the right order) volume of History of Private Life. It’s probably one of the best series about history ever written, especially if you’re interested in social changes, not the fates of battles and wars. And if there’s some study area I’d love more than social and cultural history, I haven’t found it yet.
