The University of Minnesota Duluth Kathryn A. Martin Library Archives and Special Collections includes the Northeast Minnesota Historical Center Collections that document regional history. The NEMHC Center was organized in the 1970s as one of the Minnesota Regional Research Centers in collaboration with the Minnesota Historical Society. In 2007, sole responsibility for the Center's operations was assumed by the University of Minnesota Duluth Library. In 2011, the Library consolidated archival and special collections services and holdings to form the Archives and Special Collections unit. The NEMHC Collections hold photographs, maps, manuscripts, business records and other documents that tell the story of the development of the city of Duluth and Minnesota's four northeast counties - St. Louis, Lake, Cook and Carlton. Images, maps, and documents from the NEMHC Collections are now in Minnesota Reflections, including photographs from the Paul B. Gaylord collection which depict the earliest development of downtown Duluth, the Louis P. Gallagher studio of early Duluth harbor panoramas and the work of photographers that captured images of the lumber industry. Project images include the landscape work of George A. Newton and Minnesota Ojibwe by Stella Stocker.
