I sit in front of my wall of learning. (You know, a bookshelf filled with books that one day will make a learned backdrop for my tv spots.) I have read (most of) them... but they are so specialized that they don't get to come out in heavy rotation day to day.
There are some books I have in front of me, on my desk, for me to oogle over daily. And I do. Here are two of them. The appropriately named The Politics Book and The Economics Book.
They are both by DK publishing, and cover political and economic theory. I use them frequently. When I need a quick brush up on Pinochet & Hayek... they are my saviors.
They are conscise; they are interconnected. They give theory, and then site real world application. They have great visuals. They are written in text that is accessible to students. They are FUN! (as fun as this stuff can be).
