Biblioteca Civica Bertoliana, Conservation library in Vicenza, Italy

The Biblioteca Civica Bertoliana occupies the former convent of San Giacomo in contrà Riale, refitted by engineer Dondi Dall'Orologio and inaugurated on 23 January 1910. Its central headquarters holds about 450,000 volumes, 200,000 of them printed between 1501 and 1830, plus 3,550 manuscripts and some 750 periodical titles.

In 1696 the jurist Giovanni Maria Bertolo left his roughly 9,000 volumes to Vicenza on condition they be made public in a worthy building. The collection was installed in the Palazzo del Monte di Pietà, completed in 1706 and enlarged by Francesco Muttoni, and opened to the public in 1708 as the Bertoliana, named for its founder, who died before the work ended. In 1908 the engineer Dondi Dall'Orologio began converting the former Somaschi convent of San Giacomo in contrà Riale, inaugurated as the library's home on 23 January 1910.

The library is named after jurist Giovanni Maria Bertolo, who in 1696 donated his collection to Vicenza on condition it be made public. Its holdings include the Nievo family archive and library, given by ambassador Lelio Bonin Longare between 1924 and 1933, rich in manuscripts, incunabula and 16th-century editions.

The main branch occupies the former San Giacomo convent in contrà Riale 5, where the entrance stair was moved between 1950 and 1959 to create storage and public rooms. The urban system also runs seven branch libraries across the municipality, the first opened in 1965 at Villaggio del Sole. The municipal historical archive has been managed by the library since 1881.

In April 1945 the library's director had the most precious holdings walled up in the basement of the Sanctuary of Monte Berico, with part sent to Venice; the last risky transfer took place on 12 April 1945, and a month later the material began returning to the former convent of San Giacomo.
