The Wilton Garden Club Collection includes a wide variety of materials, ranging from financial reports and minutes through flower show programs and plant specimens, produced and collected by the Wilton Garden Club and its members beginning several years before the club's foundation in 1921 through the present. The collection documents club history, internal organization, former and ongoing programs and activities, membership and finances, and stewardship of Wilton's Old Town Hall.
The Wilton Historical Society Wilton Historical Information Collection contains newspaper clippings and magazine articles, as well as correspondence and other original documentation that goes beyond individual or family interest to relate directly to the broader history of Wilton. The collection also houses the papers, newsletters, and minutes of select local organizations. The bulk of the collection is from the late nineteenth century through the mid-twentieth century.
