The W.E.B. Du Bois Library is one of two library buildings on campus and the tallest academic research library in the world, standing at 26 stories above ground and 286 feet (90.32 m) tall. Before its construction in the late 1960s, Goodell Hall was the University library, which was built after the library had outgrown its space in the 1885 "Old Chapel" building. Originally known as Goodell Library, the building was named for Henry H. Goodell, who had served as College Librarian, Professor of Modern Languages and English Literature, and eighth President of the Massachusetts Agricultural College. The Library is well regarded for its innovative architectural design, which incorporates the bookshelves into the structural support of the building. It is home of the memoirs and papers of the distinguished African-American activist and Massachusetts native W. E. B. Du Bois, as well as being the depository for other important collections, such as the papers of the late Congressman Silvio O. Conte. The library's special collections include works on movements for social change, African American history and culture, labor and industry, literature and the arts, agriculture, and the history of the surrounding region.
