Special Collections also has items that focus on Broadway Musicals, including those by Martin Gottfried, in which he describes costume and stage design, choreography, actors, and directors, and color photographs showing productions of various Broadway musicals. In one of Gottfried’s introductions he wrote "When any theatre work is performed, it becomes a living organism with a life spirit of its own." A musical is a large production of dancers, music, and theatre that takes a life of its own, and is meant to draw you in to experience the expression that the director and actors have envisioned.
