The project is called DigitaVaticana and now has over 4700 digitized manuscripts, including the fifth-century Vatican Virgil (Ms. Lat. 3225)."Digita Vaticana Onlus is a non-profit organization founded in 2013 to promote the conversion of the Vatican Library manuscripts into digital format. The Association is raising the necessary funds to guarantee the digitization of over 80,000 manuscripts held in the Vatican Library and is developing venues of communication to disseminate and articulate the value of these important historical documents, so as to improve the visibility of the project and its supporters."
