In 1960 or so, Professor Perry C. Van Arsdale was helping his 7-year-old granddaughter researching the Santa Fe trail. He found his granddaughter's textbook to have some number of errors. He set off to create a map of pioneer history (prior to the 1900's), using his own knowledge and information from judges, sheriffs, and descendants of historical figures. This was his start in creating the Pioneer New Mexico map, which would contain 300 towns that no longer exist, old trails of all sorts (including the three historic Santa Fe trails and various camel routes), locations of minor squabbles and major battles, and because he couldn't fit everything on the maps, he also included extensive notes in the corner of the map.

The Civil War Preservation Trust has a wonderful page of assorted American Civil War maps. Includes the excellent CWPT topographical maps [viewable online, download .pdf requires free registration], and historical maps. My favorites are the animated maps, on the map of the First Day of Chancellorsville you can toggle between the topo map and a present-day satellite view so you can see the effects of modern development on the battlefield.
