Galileo//thek@ is an integrated archive of Galilean resources easy to consult thanks to a refined search system. It could be described as a thematic Digital Library formed of texts, images, documents, and bibliographical records integrated with one another, plus chronological indexes of names and subjects, and lexical tools. Galileo//thek@ documents every aspect of the life, cultural activity and fortunes of the Tuscan scientist, and of the context in which he operated. This new model of digital library, resulting from the collaboration of numerous scholars, is kept constantly updated by the Museo Galileo, also by utilizing contributions furnished through the interaction of users. Though offering a body of data which tends to be complete, Galileo//thek@ is, by its nature, an ongoing project that is constantly enriched thanks to contributions from its users.
