The Department of Drawings and Prints boasts more than one million drawings, prints, and illustrated books made in Europe and the Americas from around 1400 to the present day. Because of their number and sensitivity to light, the works can only be exhibited for a limited period and are usually housed in on-site storage facilities. To highlight the vast range of works on paper, the department organizes four rotations a year in the Robert Wood Johnson, Jr. Gallery. Each installation is the product of a collaboration among curators and consists of up to 100 objects grouped by artist, technique, style, period, or subject.
