I have only visited three so far: the Reagan Library in Simi Valley, California; the Nixon Library in Yorba Linda, California; and the LBJ Library in Austin, Texas.
My favorite was probably the LBJ Library because of my admiration of LBJ and I feel like the spirit of that Presidential Library is what all Presidential Libraries should strive for. Admission is free and the LBJ Library gives a thorough examination of LBJ’s entire life, features some great permanent and special exhibits, and also places LBJ in the context of his times. I think the LBJ Library is a better teaching library than the Reagan or Nixon Libraries.
There are different reasons why I like each of the Presidential Libraries that I’ve visited. I just mentioned the LBJ Library. What I enjoyed about the Reagan Library were many of the artifacts on display, as well as Air Force One and Marine One. The Nixon Library, oddly enough, seemed to be the most intimate of the Presidential Libraries I’ve visited. After I visited the Nixon Library (and his birthplace, which is uniquely located on the grounds of his Library), I felt like I knew Richard Nixon better.
