This guide to the Joseph Downs Collection of Manuscripts and Printed Ephemera, named for Winterthur's first curator, provides descriptive information for the primary research material held in the collection. The Downs Collection acquires materials from the mid seventeenth century through the twentieth century that document American lifestyles, concentrating on the domestic scene and activities within the household and art. It includes such items as diaries, business accounts of craftsmen whose products decorated dwelling houses, family papers, tax records, construction of homes, artists' sketchbooks, wills and household inventories, children's toys and games, and scrapbooks and journals. Items from individuals famous in American history rest alongside materials from people who led routine lives yet still contributed to the development of America. An extensive microform collection, including copies of material owned by other public repositories and private individuals, supplements the manuscript holdings.
