The Biblioteca Marucelliana in Florence is a library specialising in the arts and humanities that has been open to the general public since the middle of the 18th century. Its founder, Francesco Marucelli, willed his large collection of books to the library. In 1783, the last member of the Marucelli family, Francesco di Roberto Marucelli, left the library around 2500 drawings and 30,000 engravings, and these are now being re-catalogued. The first volume of the engravings can already be consulted on a CD called PRISMA, and the records for the drawings, accompanied by digital images, will be put on a database which it is hoped will be available to scholars worldwide in 2010.
