Jennifer,
There are many fine books out there about Ronald Reagan. I would point you first and foremost to his autobiography
An American Life. There is the straight story right from the horse's mouth. There are other collections of Reagan's own writings such as
Reagan in his Own Hand and {Reagan, A Life in Letters[/i]. Those are pretty deep books and may help you get lost in research though. I know there is a collection of Reagan's speeches available at
www.reagan2000.com. If you have a more specific topic, that would help narrowing down the list of resources.
Good luck.
