[RJNorton]

The book Gene mentioned is an invaluable resource. It covers every state, city, place, etc. Lincoln was ever in during his life. It mentions hotels he stayed in, street locations of private homes he stayed in, locations of his speeches, etc. Mary's travels (in the USA, not Europe) are covered also. The book by Don Davenport is also good, but it's not as complete as Ralph Gary's.
