Library of Engeneering of the Polytechnic University of Milan, Academic public library at Polytechnic University, Milan, Italy

The Engineering Library of the Polytechnic University of Milan is located on the university campus and focuses on technical literature, research papers, and digital resources in engineering fields. The building contains computer workstations, study areas, and space for group work in modern facilities.

The Engineering Library was founded in 1864, its first core being the 3,500 volumes of Francesco Brioschi's personal collection, the founder of the Polytechnic University of Milan. In September 1927 it moved into Building 1, the Rettorato, where it stayed until 31 July 2017, when it merged with the Central Architecture Library to form the Biblioteca Campus Leonardo. By 1937 it held over 40,000 volumes; in 1953 the heirs of mathematician Gabrio Piola donated his library.

The library keeps the personal collection of Francesco Brioschi, founder of the Politecnico, and the archive of Niccolò Tartaglia, the 16th-century mathematician. Its special funds, including those of Paolo Frisi and Gabrio Piola, are consulted today at the university's Archivi Storici and Biblioteca Storica.

The facility is freely available to university students and staff, while external visitors need prior authorization. Those coming from outside should check with the university administration beforehand to learn what steps are necessary.

Among the special collections are the archive of Niccolò Tartaglia, the 16th-century mathematician who studied the solution of cubic equations, and the library of Gabrio Piola, donated by his heirs in 1953. These fonds are now consulted at the Politecnico's Archivi Storici and Biblioteca Storica.
