I'm outsourcing this week's link round-up to KirstyEvidence, a blog on research and international development I only recently discovered. Her Twelve Days of Evidence post starts with 12 non-fiction books worth buying, 11 tweeps to follow, and so forth. It's good stuff, so click through and enjoy some light holiday reading. (Plus, it gets me in more of a holiday mood than the Michael Bolton Christmas album playing in the Addis hotel lobby where I started writing this post. Ugh.)
