The Vatican Library (above), 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 more 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.
