Thanks in part to its early role in the development of printing in Rome and the surrounding area, the Biblioteca Apostolica Vaticana possesses the fourth largest collection of incunabula in the world, with almost 8900 items, including many of the first books printed in Rome between 1467 and 1473. These include texts on a wide range of subjects, from scripture and scriptural commentary to contemporary science, philosophy, and medicine. For the launch of the project, the Vatican has digitised a range of psalters and Bibles printed in Italy and Germany, including a Gutenberg Bible and the beautiful Stamp. Ross. 283, which contains full-colour woodcuts.
