The Vatican Library is the library of the Holy See and one of the oldest libraries in the world. It was established in 1475, but existed in early forms roughly since the beginning of the Catholic Church. The library has added to its collection over the years primarily through bequests and gifts. The Vatican Library currently holds over 1.1 million books, 75,000 manuscripts, and over 8,500 incunabula. The library owns the oldest complete manuscript of the Bible and many other important medieval works.
