They are creating a digital archive of the history of North Dakota. A staggering amount of work and one for which I am grateful. My ancestors spent limited time in North Dakota but I found much information in this rich resource!
Creator: The Digital Horizons group is a consortium including Concordia College Archives, Moorhead, Minn.; NDSU Institute for Regional Studies & University Archives, Fargo, N.D.; Prairie Public Broadcasting, Fargo, N.D.; and State Historical Society of North Dakota, Bismarck, N.D..
Published: Beginning 2007, North Dakota, USA
The site boasts 45000+ searchable items in their North Dakota state history catalogue. They have a digitized collection of around 400 local history books produced by various regions, organizations and towns through the years.
Go to the site and plug in your ancestors names and places!
