The Bucks County Civil War Round Table Library and Museum in Doylestown, Pennsylvania was established by the Bucks County Civil War Round Table in 2003 to serve as a center for the advancement of history and Civil War research and the preservation of Pennsylvania's participation in America's great conflict. The Museum and Library houses approximately 5 linear feet of archival materials, dating from 1861 to the present, although most materials date from 1861 to 1900. Primary source materials include correspondence, administrative and financial military records, and photographs. There is also some accumulated secondary-source material, such as research notes, newspaper clippings, narrative histories, and other items, most of which relate to those involved in the Doylestown-based 104th Pennsylvania Volunteer Infantry regiment, their descendants, and the monument to the 104th regiment in the Borough of Doylestown.
