The Automobile Blue Book was an American series of road guides for motoring travelers in the United States and Canada published between 1901 and 1929.
Directions were not necessarily intended to be the shortest or fastest connection between each city, but to provide interesting scenery and opportunities for rest and maintenance along the route.
Early pathfinders were actually bicyclists, but eventually automobile clubs – especially those of the AAA – became the major source of routes compiled by the Blue Book.
