1. LIBRARY OF CONGRESS -- WASHINGTON D.C., USA
The Library of Congress in Washington DC is essentially both the national library of the U.S. and the country's oldest federal cultural institution. Though it consists of only three buildings, it is the largest library in the world for shelf space and number of volumes. While open to the public for on-site research and as a tourist attraction, as the research institution of Congress, only members of Congress, Supreme Court justices, and other specified government officials can check out books. The library is formally known as the "library of last resort" in the U.S., charged with making certain items available to other national libraries if all other means have been exhausted. The library's holdings are vast, including more than 32 million books, more than 61 million manuscripts, a rough draft of the Declaration of Independence, one of only four perfect vellum copies of the Gutenberg Bible in the world, over one million newspapers from the last three centuries, over five million maps, six million pieces of sheet music, and more than 14 millions photos and prints.
2. READING ROOM AT THE BRITISH MUSEUM -- LONDON, ENGLAND
The Reading Room at the British Museum is located in the center of the Museum's Great Court. The building's domed exterior protects a unique interior ceiling made of a special kind of papier-mache, which is another first on our list! For much of the Room's history, access was limited to registered researchers, attracting notable visitors including Karl Marx, Oscar Wilde, Mahatma Gandhi, Rudyard Kipling, George Orwell, Mark Twain, Lenin, and H.G. Wells during this time. The majority of the collection was moved to the new British Library in 2000; the Reading Room now houses an information center and a curated collection of specialty art and history titles relevant to the collections of the British Museum. The Reading Room has also been known to host long-running temporary exhibitions of its own, such as the 2006 exhibit centered on China's famous Terracotta Army.
3. VATICAN LIBRARY -- VATICAN CITY, ROME
The Vatican Library, under the ecclesiastical jurisdiction of the Catholic Church in Rome, is one of the oldest libraries in the world. Though it was formally established in 1475, its existence in early forms dates back to the origins of the Catholic Church. For nearly 600 years, the library has added to its collection through historic acquisitions, generous bequests, and gracious gifts. The Vatican Library currently holds mor than 1.1 million books, 75,000 manuscripts, and over 8,500 incunabula. Fittingly, the library owns the oldest complete manuscript of the Bible, as well as many other significant works from medieval times.
