Syracuse University's main library is the Ernest S. Bird Library, which opened in 1972. Its seven levels contain 2.3 million books, 11,500 periodicals, of manuscripts and rare books, 3.6 million microforms, and a café. There are also several departmental libraries on campus. Many of the landmarks in the history of recorded communication between people are in the university's Special Collections Research Center, from cuneiform tablets and papyri to several codices dating from the 11th century, to the invention of printing. The collection also includes works by Galileo, Luther, John Calvin, Voltaire, Isaac Newton, Descartes, Francis Bacon, Samuel Johnson, Thomas Hobbes, Goethe, and others. Other collections of note include Rudyard Kipling first editions and an original second leaf of the Gutenberg Bible.
