The presentation is like looking through a book on a computer. The CD-ROM works in PCs (WIN 2000/XP/Vista/7/10) and Macs and is self-starting. The images can be printed out if you chose.
Illinois Central Depots in and Around Iowa features 45 images from photographs, slides and postcards in states of Iowa, Wisconsin, Minnesota and South Dakota. In some instances, there are both historical and contemporary views. The depots and structures are grouped by state.
