If youre interested in viewing, and especially comparing, USGS topo maps, the USGS Historical Topographic Map Explorer is a must see. In this example video, we start with the 1902 topo around the University of Maine, and transition to the 1998 topo of the same area. Youll notice the addition of roads, houses, railroad tracks and the expansion of the campus. Check out the Explorer here: historicalmaps.arcgis/usgs/.
