largest university library and the first institutional library in what became the United States, established when John Harvard (Harvard, John), a young Puritan minister, left his collection of 260 volumes to the new Harvard College in Cambridge, Mass., in 1638. The core of the collection now contains 10,000,000 volumes, housed in three adjacent buildings. There are works for advanced study and research, rare books and manuscripts, and a reading collection for undergraduates. Beyond this core are scores of books in departmental and special libraries, the most notable being those of law, business, biological sciences, Chinese and Japanese languages and culture, astronomy, anthropology, and ethnology. Among the special holdings are remarkable collections of books and manuscripts by John Keats, Emily Dickinson, Ralph Waldo Emerson, James Russell Lowell, and Oliver Wendell Holmes; a theatre collection unique for its 18th- and 19th-century British and American materials; a Theodore Roosevelt collection; and the John F. Kennedy School of Government Library, containing a large archival collection of the papers of John and Robert Kennedy and those of Ernest Hemingway.
