The Archives of American Art at the Smithsonian Institution just announced a new resource for those interested art historical research: Chicago's Art-Related Archival Materials: A Terra Foundation Resource.
This project is the product of an extensive survey of the holdings of area institutions undertaken between February 2014 and April 2015. It offers records of nearly 900 individual collections of archival materials relating to American art and design, inviting primary research on the wide-ranging history of art and design in Chicago. The project has been generously supported by the Terra Foundation for American Art in Chicago, and it was made possible by the cooperation and expertise of archivists, librarians, curators, and other staff members at each of more than 75 area institutions.
