national library. The Strasbourg municipal library had been marked erroneously as "City Hall" in a French commercial map, which had been captured and used by the German artillery to lay their guns. A librarian from Munich later pointed out "...that the destruction of the precious collection was not the fault of a German artillery officer, who used the French map, but of the slovenly and inaccurate scholarship of a Frenchman." The municipal library Bibliothèque municipale de Strasbourg (BMS) administrates a network of ten medium-sized librairies in different areas of the town. A six stories high "Grande bibliothèque", the Médiathèque André Malraux, was inaugurated on 19 September 2008 and is considered the largest in Eastern France. Incunabula As one of the earliest centers of book-printing in Europe (see above: History), Strasbourg for a long time held a large number of incunabula — books printed before 1500 — in its library as one of its most precious heritages: no less than 7,000. After the total destruction of this institution in 1870, however, a new collection had to be reassembled from scratch. Today, Strasbourg's different public and institutional libraries again display a sizable total number of incunabula, distributed as follows: Bibliothèque nationale et universitaire, ca. 2,120, Médiathèque de la ville et de la communauté urbaine de Strasbourg, 349, Bibliothèque du Grand Séminaire, 238, Médiathèque protestante, 66, and Bibliothèque alsatique du Crédit Mutuel, 5. Transport Train services operate from the Gare de Strasbourg, the city's main station in the city centre, eastward to Offenburg and Karlsruhe in Germany, westward to Metz and Paris, and southward to Basel. Strasbourg's links with the rest of France have improved due to its recent connection to the TGV network, with the first phase of the TGV Est (Paris–Strasbourg) in 2007, the TGV Rhin-Rhône (Strasbourg-Lyon) in 2012, and the second phase of the TGV Est in July 2016. Strasbourg also has its own airport, serving major domestic destinations as well as international destinations in Europe and northern Africa. The airport is linked to the Gare de Strasbourg by a frequent train service. City transport in Strasbourg includes the futurist-looking Strasbourg tramway, which opened in 1994 and is operated by the regional transit company Compagnie des Transports Strasbourgeois (CTS), consisting of 6 lines with a total length of . The CTS also operates a comprehensive bus network throughout the city that is integrated with the trams. With more than of
