Bibliothèque-Musée de l'Opéra National de Paris

The Bibliothèque-Musée de l'Opéra National de Paris is a library and museum of the Paris Opera and is located in the 9th arrondissement at 8 rue Scribe, Paris, France. It is no longer managed by the Opera, but instead is part of the Music Department of the National Library of France (Bibliothèque nationale de France or BnF). The Paris Opera Library-Museum is open daily; an admission fee is charged.

The Library-Museum is housed in the Palais Garnier in the Rotonde de l'Empereur, a pavilion on the west side of the theatre, which was originally designed to be the private entrance for Emperor Napoleon III. Thus, the Emperor's could directly enter in the building and avoid any assassination attempt. The library is located near the intersection of the rue Scribe with the rue Auber, streets which are named after the librettist Eugène Scribe and the composer Daniel Auber, both of whom had works performed by the Paris Opera.

After the Emperor's death in 1873 and the proclamation of the French Third Republicin 1870, President Mac-Mahon refused to use this Pavilion as a private space for the head of state. Charles Nutters succeeded in compelling Charles Garnier in transforming the pavilion into a space for the conservation of the Opera's books and archives.

From the time of the creation of the Paris Opera in 1669 until the middle of the 19th century there was no official entity in charge of the preservation and management of archival materials produced by the activities of the Opera and its associated theatre. The creation of an archives service and a library was integrated into the project entrusted to the architect Charles Garnier for the construction of a new opera house to replace the Opera's former theatre, the Salle Le Peletier. Thus the current Paris Opera Library-Museum traces its origin to two former services of the Opera, the archives and the library, each created in 1866. At that time, the Opera director became an entrepreneur. Expenses exceeded the receipts, and the government needed a strong man to run the establishment but was afraid that the archives would be sold to generate money.
