Minnesota is best known for supplying the steel industry with iron ore, but there were and are a number of Minnesota companies involved in making steel or related to the industry. These companies are Interlake Iron Zenith Furnace, USS Duluth Works, North Star Steel, Koppers Coke and American Iron & Supply. The 223 images are from photos, slides and postcards and range from the early 1900s to the 1990s. Also on the CD are publications and histories of the companies.
The presentation is like looking through a book on a computer. The CD-ROM works in PCs (WIN 2000/XP/Vista/10) and Macs and is self-starting. The images can be printed out.
