The Library was originally founded in 1451 AD and holds over 80,000 manuscripts, prints, drawings, plates and books printed prior to 1500 AD. The titles are all written throughout history by people who had different faiths or religions, from all over the world. Not only are paintings, religious iconography and books being published online, but also letters by / from important historical figures, drawings and notes by artists and scientists such as Michelangelo and Galileo, as well as treaties from all eras in history.
Finding all of the new digitized material is not easy; the library has a few samples online, but honestly it's tedious right now to view the rest. Users have to search the database manually by clicking on each title and scanning through all the pages in each book. By the end of the year, a new rendering engine is going to be implemented with a more robust site-wide searching system.
In order to properly digitize the rest of the library, the Vatican is estimating that it will cost €50 million and take fifteen years. They are looking for corporate sponsors and normal people who want to see this work. One of the ways they are attracting corporate sponsors is to hold exclusive fundraising events. In June 2014 they had one and gave attending guests an exclusive guided tour of areas generally closed to the public, including the Library halls, laboratories and the caveau where the manuscripts are safeguarded, with dinner in the Sistine Hall. They also seeking donations of €5 to save a single page in a manuscript, while donations of at least €1,000 will see the backer included on the official supporters list.
