"The physical and geographic expansion of the Society's facilities was complemented by increased professionalism of its curatorial operations and an important topical expansion of its collections. Beginning in the late 1960s the Society began aggressive programs to acquire and preserve documents and artifacts that represented the histories of Northeast Ohio's diverse populations. Specific programs were established in African-American, Jewish, Italian, Irish, LGBT, labor, and other areas of community history which have provided it with unparalleled resources relating to urban, industrial, immigration, and family history. These provide a critical complement to its collections on the pioneer settlement and early growth of the Western Reserve as well as to major topics such as the American Civil War, decorative arts, genealogy, and automotive and aviation history."
