Presidential Libraries are important research facilities, and the museums continue to create sophisticated and popular exhibits. As each Presidential administration leaves office, the size of Library holdings increases exponentially.
Each Presidential Library offers onsite reference service in their research rooms, (Public Link) online reference service through their websites and traditional reference service through e-mail, telephone and U.S. mail. Through these mechanisms, Presidential Libraries serve researchers and visitors from all walks of life. They provide guides, lists of holdings, finding aids, access to primary resources, and copies of those resources through use of photocopiers, digital cameras, and digitized scans available online.
