Much more fun than the average stuff C-Span shows are the BookTV episodes that air on the weekend. Here are a few episodes I've enjoyed that deal with history:Destiny of the Republic
by Candice Millard
I liked this episode quite a bit since it's a fascinating subject with a very personable author. If you've ever wondered about President Garfield and his assassination I highly recommend it.
