This group of more than two thousand accessioned works of art, books, manuscripts and archival materials constitutes a collection within a collection. It contains 1,791 original illustrations and preparatory materials for 96 children's books, 367 additional examples of original art for magazine covers and Christmas cards, miscellaneous sketches, books in English and other languages, correspondence and manuscripts.

Original art and books are under the care of the Department of Prints and Drawings of the Zimmerli Art Museum. Roger Duvoisin's manuscripts and correspondence are preserved in the Special Collections Department, at Alexander Library, the main library of the Rutgers University system.

Louis Fatio Duvoisin, the artist's widow, formally donated illustrations and other materials to the Rutgers Collection between 1982 and 1991. Roger Duvoisin, son of the artist, made additional donations in 1995.

Original art and preparatory materials created by Roger Duvoisin are frequently included in the exhibition and education programs of the Zimmerli Art Museum. The work of Roger Duvoisin was the subject of a retrospective exhibition organized by the Zimmerli Art Museum in 1989. A catalogue, Roger Duvoisin: The Art of Children's Books, by Ellin Greene, documents this exhibition.
