My interest in maps, history & genealogy has led me to compile these old maps on cd for others like myself.  They are a great resource to see how things were in the past.  Many processes have changed the lay of the land, including highways, natural disasters, mining, etc.

These maps are great for historical and genealogy research.  Find old roads, rail lines, steamboat routes, town names...even cemeteries and churches. 

Many of these maps may be hard to find even in university libraries, some are reprints of the originals by USGS and some may have been in poor condition when scanned because of their rarity.  Also some where not scanned in there entirety because they represented uncharted areas such as open ocean or Canada.  They range in date from the 1890's to the 1950's.
