The author inside a replica of the Oval Office at the Jimmy Carter Presidential Library and Museum.Talia Lakritz/Business InsiderI visited the Jimmy Carter Presidential Library and Museum in Atlanta last year.I was surprised by the historical significance of the artifacts on display and a celebrity cameo.I also didn't know that presidential libraries have stamps you can collect in a special passport.As someone who often writes about US presidents, first families, and White House history, I've wanted to visit a presidential library for a while.Not every former US president has built one — only 15 have done so since Congress established the practice with the Presidential Libraries Act in 1955.
