Repository Details

Part of the Houghton Library Repository

Houghton Library is Harvard College's principal repository for rare books and manuscripts, archives, and more. Houghton Library's collections represent the scope of human experience from ancient Egypt to twenty-first century Cambridge. With strengths primarily in North American and European history, literature, and culture, collections range in media from printed books and handwritten manuscripts to maps, drawings and paintings, prints, posters, photographs, film and audio recordings, and digital media, as well as costumes, theater props, and a wide range of other objects. Houghton Library has historically focused on collecting the written record of European and Eurocentric North American culture, yet it holds a large and diverse number of primary sources valuable for research on the languages, culture and history of indigenous peoples of the Americas, Africa, Asia and Oceania.
