The focus of this collection is as-built or record drawings for projects circa 1900-present. Some older drawings—the oldest dating from 1840—may include design development and schematic design drawings. The majority of the drawings are on traditional supports such as linen, vellum, paper and Mylar. A growing portion of the collection is available electronically, as CAD and TIFF files.
