Royal Library of Belgium. The Royal Library of Belgium is the national library of Belgium. The library has a history that goes back to the age of the Dukes of Burgundy. In the second half of the 20th century, a new building was constructed on the Mont des Arts in central Brussels, near the Central Station. The library owns several collections of historical importance, like the famous Fétis archives, and is the depository for all books ever published in Belgium or abroad by Belgian authors. There are four million bound volumes in the Royal Library, including a rare book collection numbering 45,000 works. The library has more than 700,000 engravings and drawings, 150,000 maps and plans, and more than 250,000 objects, from coins to scales to monetary weights. This coin collection holds one of the most valuable coins in the field of numismatics, a fifth-century Sicilian tetradrachm. The library also houses the Center for American Studies, a rich American Studies collection of 30,000 books in open stacks, as well as U.S. newspapers and databases. The Royal Library is open for reference only. Patrons must be at least eighteen years of age and must pay an annual membership fee.[ Made up of around 60 smaller collections concerning music, the music department is a significant resource for the study of music history in Belgium and abroad. The most representative pieces are part of collections of François-Joseph Fétis, Eugène Ysaÿe, Henri Vieuxtemps, Marc Danval, Yves Becko, Denijs Dille, Flor Peeters or also Edgar Tinel. The Royal Library of Belgium's Music Division is considered one of Belgium's most important centers for the preservation and study of music-related documents. The Music Division maintains a rich and varied collection composed of hundreds of thousands of manuscript and printed scores, about 100,000 sound recordings, a large collection of correspondence, printed works, concert programmes, posters, photographs and other iconographic documents, not to mention varied objects such as medals, busts, casts, music instruments. Although most music-related documents in the Royal Library are held in the Music Division, certain additional works are held in the Manuscript, Rare Books and Prints and Engravings divisions of the Library. The Music Division was founded in 1965, building upon the more than 5,000 printed and manuscript documents that made up the private collection of the important 19th century Belgian musicologist François-Joseph Fétis, acquired by the Royal Library in 1872. This Fétis Collection is an important source for the study of early music, and holds a number of important documents such as the autograph manuscript of Johan Sebastian Bach's BWV 995, Suite in G minor. Among the oldest pieces of the Fétis Collection are several late 15th century manuscripts by theorist Johannes Tinctoris.
