Museo Galileo library

The Museo Galileo library is presently composed of nearly forty thematic digital collections.
The digital collections are a result of a profitable collaboration with specialized scholars representing different fields related to the history of science and technology. The most significant part of the collection is represented by the Galilean corpus (Galilean Digital Library, Galileo’s Disciples, Accademia del Cimento, Galileo’s Library, Galilaeana online) which represents a fundamental reference in the field of Galilean Studies. Digital records dedicated to the study of perspective, ancient mathematics, with a strong connection to science or published in occasion of special exhibitions enrich the documental ensemble offered by the digital library. All the digital collections provide a free access, except the correspondence of Roger Giuseppe Boscovich (1711-1787) and the digital library on Leonardo da Vinci that require an authorisation from the direction.
