Thanks to Kimberly Powell at genealogy.com for this very helpful article.
Quote: You can overlay any historic map in Google Maps or Google Earth, but getting everything to match up accurately through geo-referencing can be quite tedious. In some cases others have already done the hard part, making available free downloads of historical maps sized, geo-referenced and ready for you to import directly into Google Maps or Google Earth. http://genealogy.about.com/od/mapping_tools/tp/historical-map-overlays.htm
