Dance Notation Bureau (DNB)The DNB mission is to advance the art of dance through the use of a system of notation. The DNB Library maintains the world's most substantial collection of original Labanotated dance scores. Along with the DNB-produced scores, the Library collects and houses other materials needed to stage the dances, including music scores, audiotapes, videotapes, production information, historical information, and anything else pertinent to a dance. It is devoted to housing and preserving these materials and to making them as accessible as possible for the purposes of continued performance, classroom use, and scholarly research.
