See BookTV’s incredible list of best books of 2009, including links to tons of similar lists on other sites.
One reason that I love BookTV: they focus on non-fiction in three two of my favorite subject areas: history and economics. The third focus is politics, which can be interesting when it centers on policy and the results of same, or when written by humorous people like P.J. O’Rourke or Mark Twain. Otherwise … not so much.
