The library, which has been a part of the institute since its foundation, was completely remodelled in 2002, when it was moved to the third floor of Palazzo Castellani. The new architectural display was awarded the “Bibliocom Biblioteche in vetrina” prize. The library houses about 150,000 works concerning the history of science. The antique book collection consists of nearly 5,000 works. It includes the Medici-Lorraine Collection, comprising scientific books mostly about physics and mathematics, gathered by Tuscan dynasties over five centuries. The library is also home to several 18th- to 20th-century archival collections and a photo archive related to the history of the museum's collections, ancient instruments and places of scientific interest. The contemporary collection includes books in Italian and the major European languages and has an annual growth of about 1,800 new acquisitions. All of the library's material can be searched in the online catalogue. Among the library's activities are the compiling of bibliographies –notably the International Galilaean Bibliography– and the cataloguing of documents relevant to the history of science, even those not in the library's possession. In 2004, a
Digital Library was created to preserve and publish digital collections of historical scientific interest. ==The Multimedia Lab==
