Digital Horizons was established in 2007 by a consortium that includes Prairie Public Broadcasting, the State Historical Society of North Dakota, and several other organizations. The goal of their work is to provide and maintain access to "a wide range of historical and significant content related to North Dakota and Minnesota." Visitors can use the search engine here to look for items by general subject heading or collection. All told, there are over fifteen collections included in this archive, including "Korean War Propaganda Leaflets", "Dakota Lithographs and Engravings", and "North Dakota Blue Books". For those looking for a place to start, they can take advantage of the "Popular Searches" list, which includes topical headings such as "floods", "bonanza farms", and "homesteading". This last heading is a great place to check out, as visitors will find evocative (and sometimes quite lonely) photographs of 19th century homesteads.
