I'd like to learn more about all the presidents with a chapter on each, getting to office, their time there, their time after etc. Nothing huge as I know there is a lot to be said on the subject. I have never been able to find one which covers every president.
There was a great set of documentaries called "The Presidents" by The History Channel a few years back that does a piece on each president. They have one at the end I believe that talks about the first ladies as well.
