Louis Notari Library, National library in Monte Carlo, Monaco

The Louis Notari Library is a national library in Monte Carlo that houses a large collection of books, audio materials, and digital documents in several languages. The building sits on Rue Louis Notari and functions as a research and reading center for the region.

Founded by Prince Albert I in 1909, the library became Monaco's legal deposit and copyright library in 1925. In 1980 it was named after Louis Notari, author of the first publication in the Monegasque language. Its collections grew with Notari's literary archives, donated in 2003, and the private archives of scholar Louis Canis (1891–1973), added in 2010.

Since 1980 the library has borne the name of Louis Notari (1879–1961), the Monegasque writer behind the first publication in the Monegasque language. Its collections include Notari's literary archives, donated in 2003, and since 2010 the private archives of the scholar Louis Canis (1891–1973).

The library is located on rue Louis Notari and has different opening hours depending on the season. It is helpful to check the hours before visiting, as they change between the summer months and the rest of the year.

The library maintains digitized copies of regional documents and archives that are made available online. This allows people to access local materials from a distance that would otherwise be difficult to find.
