The working library of noted railroad executive John W. Barriger III (1899-1976) was acquired in 1982, the generous donation of his family. Widely recognized as one of the twentieth century's best-known and most distinguished railroad executives, Mr. Barriger was also an avid scholar, book collector, and photographer. His collection of books, papers, photographs, and memorabilia - collected over an active career of 50 years - forms the nucleus of the Library's railroad collections, one of the largest rail transportation collections in the world.
